Subject: [PATCH] Add double-click to rename layers, extract useInlineRename
 composable

- New useInlineRename composable: shared editing state, commit logic,
  and keyboard handling for inline rename across panels
- LayerTree: double-click a layer name to rename inline
- PagesPanel: refactored to use useInlineRename, removing duplicate code

Closes #57
