fix(ai): add close-button aliases (dismiss/cancel/remove/closebutton/expand/collapse → x / maximize-2 / minimize-2)

Why: end-to-end test of "design a notification card with dismiss x
button" surfaced that MiniMax-M2.7 emits a path node named "Dismiss
Icon". Tokenisation gives "dismiss" but Lucide doesn't have a `dismiss`
key — the resolver fell through prefix/substring fallbacks and wrote
the placeholder lucide:circle, leaving the card with a hollow ring
where the X should be.

What: 5 new aliases added in lock-step to icon-dictionary.ts (client
commonAliases) + icon.ts (server NAME_ALIASES per existing comment):
  - dismiss   → x       (close button intent)
  - closebutton → x     (compacted from "Close Button Icon")
  - cancel    → x       (cancel-action close icon)
  - remove    → x       (remove-action close icon)
  - expand    → maximize-2
  - collapse  → minimize-2

NOT aliased: `cross`. Lucide already ships a `cross` icon (the
Christian-cross shape) and overriding it would lose that geometry.
"Cross" disambiguation is left to the model — if it really means a
close button, telling it to write "Dismiss Icon" / "Close Icon" via
the icon-catalog skill is enough.

Tests: 3 new it.each cases (Dismiss / Cancel / Remove Icon → /x/).
1069 / 1069 AI tests pass (was 1066; +3).
