* Update RawStringContent encoding in JsonContentFactory (#6786)
* Update RawStringContent encoding in JsonContentFactory
Modified the instantiation of `RawStringContent` to use a
new `UTF8Encoding` instance with `encoderShouldEmitUTF8Identifier`
set to `false`, affecting the handling of the UTF-8 byte order
mark (BOM) in serialized JSON content. Fixes a bug with content length being different than expected.
* Refactor JsonContentFactory to reuse UTF8Encoding

* Enhance thread safety with ConcurrentDictionary usage (#6760)
* Enhance thread safety with ConcurrentDictionary usage
Replaced `IDictionary` with `ConcurrentDictionary` for
both `_scheduledTasks` and `_scheduledTaskKeys` to

Modified the `LocalScheduler` class to enhance the removal process of scheduled tasks from the `_scheduledTaskKeys` collection. The removal operation now captures the result in a variable and includes a conditional check to log a warning if the task was not found, improving error handling and debugging capabilities.
* Refactor task removal in LocalScheduler
Updated the removal process for scheduled tasks in `_scheduledTasks`.
The new implementation collects all corresponding keys and attempts to remove them individually, logging warnings for any failures. This enhances error handling and provides better debugging information.

* Enhance null-safety annotations across modules and refactor for improved consistency:
- Added `null!` annotations to enforce non-nullability expectations.
- Updated workflows, tests, and runtime services to handle default null values reliably.
- Removed obsolete and unused APIs, simplifying interfaces and improving maintainability.
- Refactored methods and properties for clarity, thread-safety, and consistency.
- Adjusted test configurations for code coverage tracking and integration improvements.
* Refactor activity iteration in container serialization tests to simplify type casting.
This update ensures consistency and improves clarity in specifying nullable types and default values. Replaced `default!` with `null` in various activity classes and properties to better align with modern C# nullable reference type practices.
* Add tenant awareness to bookmark handling and route resolution
Added tenant ID support across various components, including bookmark updates, route resolution, and middleware processing. This ensures that bookmark and route operations can now appropriately handle tenant-specific data, improving the system's multitenancy capabilities.
* Add Multitenant HTTP Routing feature to Tenants module
Introduced a new MultitenantHttpRoutingFeature class to the Elsa.Tenants.AspNetCore module, enhancing the tenant resolution capabilities. Moved RoutePrefixTenantResolver from Elsa.Http to Elsa.Tenants.AspNetCore and updated relevant project references and namespaces accordingly. This refactor improves modularity and separation of concerns between HTTP and tenancy features.
* Refactor route handling and tenant configuration
Removed redundant `RouteTableExtensions` and replaced with new route providers and updaters, enhancing flexibility and modularity. Introduced tenant-specific HTTP endpoint configurations for better customization and configuration management.
* Rename HttpEndpointBookmarkStimulus to HttpEndpointBookmarkPayload
Refactor various classes and methods to reflect the renaming from `HttpEndpointBookmarkStimulus` to `HttpEndpointBookmarkPayload`. Add and configure new extension methods for tenant route handling, update the route provider to support multi-tenancy, and adjust the tenants provider to bind configuration properly.
* Add HeaderTenantResolver and refactor Http namespace.
Introduce HeaderTenantResolver to resolve tenants via HTTP headers. Refactor multiple classes and interfaces to move from the Elsa.Http.Models namespace directly into Elsa.Http for clarity and consistency.
* Add Host-based tenant resolution
Implemented a HostTenantResolver to resolve tenants based on the request's host and updated tenant configurations with host information. Modified the tenant resolver pipeline and added the new host resolver to the service registrations.
* Add tenant-aware caching and accessor support
Enhanced caching by incorporating tenant identifiers into cache keys for more granular cache management. Introduced ITenantAccessor dependencies in various services to retrieve the current tenant information. This ensures that cache entries are correctly isolated per tenant.
* Reorder tenant resolvers for pipeline setup.
Reordered the tenant resolvers in the pipeline to prioritize HostTenantResolver before RoutePrefixTenantResolver. This ensures that tenant resolution is correctly aligned with host-based resolving before checking the route prefix.
* Remove unused imports
This commit eliminates redundant `using` directives across multiple files to streamline the codebase. This cleanup helps improve code readability and maintainability by removing unnecessary dependencies.
* Add error handling with fault categories and codes
The code now includes error handling through the introduction of fault categories and codes. New files containing constants for fault categories and codes have been added for different modules. FaultException has also been updated to include these properties. Changes are evident in various files where FaultException is thrown for error handling.
* Add DotSettings file for Elsa.Alterations module
A new DotSettings file is added for the Elsa.Alterations module. This includes configuration for namespace folders to be skipped during CodeInspection.
* Renamed "DefaultFaultKinds" to "DefaultFaultTypes" and updated usages
This commit renames the class "DefaultFaultKinds" to "DefaultFaultTypes" and updates all its references across the project files. The change is made keeping the more accurate naming context i.e., 'Types' suits better in the thrown exception scenarios.
This commit introduces a JSON editor UI hint to HTTP activities within Elsa Workflow. It includes creating new classes for a JSON editor options provider and a handler for this UI hint. Also, these additions are registered within the Elsa Workflow. The hint is applied to the 'RequestHeaders' and 'ResponseHeaders' input fields found in HTTP-related activity classes.
Changed a number of instances in both activities and UI Hints classes across multiple modules in the workflow core to utilize UIHints. The UI hint "DropDown" has been added to relevant input fields to improve the user interface. Special handling for Enum properties in the drop-down options provider has also been created.
* add a more generic UIHandler to customize how inputAttributes can be handle by the ui
* Add IPropertyUIHandlerResolver and update PropertyUIHandlerResolver
Introduced a new interface, IPropertyUIHandlerResolver, to resolve UI options for a property. Refactored PropertyUIHandlerResolver to implement this interface and removed the unnecessary partial class structure. Also, cleaned up some unnecessary usings in various files for better code organization.
* Refactor variable name and description in InputDescriptor
The 'uISpecifications' variable in the InputDescriptor model is renamed to 'uiSpecifications' for better readability. Additionally, the associated comment was revised to explain that the dictionary is used by the UI.
* "Refactor codebase for improved organization and cleaner architecture"
The codebase has been significantly refactored, moving several classes to more appropriate namespaces for improved organization and cleaner architecture. This includes shifting UI hint handlers, activities, and memory-related components, amongst others. The changes should improve code readability and maintainability, but as this is a broad refactoring effort, thorough regression testing is advised.
* Add CheckList UIHint with associated handler and provider
This update introduces a new UIHint called CheckList to the Elsa.Workflows.Core. This includes the necessary handler and provider classes. The handler is registered in the WorkflowsFeature.cs, and the CheckList UIHint key has been added to the InputUIHints.cs. Various associated files have been created in both the Elsa.Api.Client and Elsa.Workflows.Core project to support this new UIHint.
