feat(ux): forward to multiple rooms + live bookmark previews (P6-3)

Forward: checkbox multi-select room picker + "Send to N rooms" batch send
(Promise.allSettled). Full success auto-closes; partial failure keeps the dialog
open with a "Forwarded to X/N — failed: …" summary and prunes the selection to
only the failures (retry won't duplicate to already-sent rooms). Content builder
extracted to a unit-tested forwardContent.ts (edit-forwarding, reply-strip,
undecryptable-refused; 4 tests).

Bookmarks: BookmarksPanel resolves each saved message's live event (useRoomEvent)
so previews reflect edits and show a deleted indicator for redactions; the stored
snapshot stays as the fallback while loading, on fetch failure, or after leaving
the room. Stored bookmark shape unchanged.

Gates: tsc/eslint/prettier clean, build OK, 665 tests. Reviewed (dup-resend on
retry + Checkbox readOnly fixed).

## UX & Composer
### Forward to Multiple Rooms (P6-3)
The Forward Message dialog is a checkbox multi-select: pick any number of rooms (search + select persist across queries) and **"Send to N rooms"** forwards in one batch (`Promise.allSettled`). Full success auto-closes; a partial failure keeps the dialog open with a "Forwarded to X/N — failed: …" summary. The forwarded content (latest edit via `m.new_content`, reply-quote stripped, undecryptable refused) is built by the shared, unit-tested `forwardContent.ts`.
### Live Bookmark Previews (P6-3)
`BookmarksPanel` resolves each saved message's **live event** (`useRoomEvent`) so previews reflect **edits** and show a **deleted** indicator for redactions, instead of the save-time snapshot. The stored snapshot (`previewText`) remains the fallback while loading, on fetch failure, or when you've **left the room**.
### Message Length Counter
A character count indicator is shown in the composer when `charCount > 0`. The counter resets to zero when switching rooms.
