Made-with: Cursor
* e2e test
* Expose focus()/blur() on WysiwygEditor handle so focus hooks work
useTextboxFocus drives focus into the composer for many flows (channel
switch, RHS open, post-submit refocus, Reply shortcut, "type to focus
main input"). It calls textboxRef.current?.focus(), but textboxRef is
the legacy <Textbox> ref and is null when the WYSIWYG editor is the
mounted composer, so every focus call becomes a silent no-op.
Add focus() and blur() to WysiwygEditorHandle, backed by editor.commands
.focus()/blur(), and pass wysiwygRef into useTextboxFocus so it picks
whichever ref is mounted. The hook keeps its existing signature for
legacy callers; wysiwygRef is optional.
Verified locally on the WYSIWYG branch:
- messaging/focus_move_spec (3/6 failing -> 6/6 passing)
- messaging/message_edit_post_clear_text_spec (0/1 -> 1/1)
- messaging/message_edit_post_history_spec (0/3 -> 1/3)
- keyboard_shortcuts/dot_menu_spec gets past the Reply-focus assertion

* e2e: coerce postMessage args to string in WYSIWYG branch
The legacy textarea path used cy.invoke('val', message) which silently
coerced numbers/undefined to strings. The WYSIWYG branch added in the
previous refactor calls message.replace() and crashes with
"TypeError: message.replace is not a function" whenever a spec passes a
non-string value, e.g. cy.uiPostMessageQuickly(0) or before-each hooks
that pass undefined.
Funnel everything through asPostMessage() so the WYSIWYG branch is just
as forgiving as the textarea branch. Loosen postMessage /
postMessageReplyInRHS / uiPostMessageQuickly typings to `unknown` to
match what callers actually pass.
Fixes failures in: copy_post_text_spec, save_post_spec,
search_filter/{after,before,future_date}_spec, and
scroll/default_images_collapsed_spec.
