Close the undo gaps, index treasure in search, and polish the ledgers

[it-rec]

A sweep of consistency improvements across the panels, closing gaps where sibling panels already had the feature.

Undo for every destructive shared-state action

Deletes broadcast instantly to the whole table, so an accidental tap used to be unrecoverable. All of these now raise the same Undo toast the other ledgers got in #262:

• Journal — removing an entry (the one text ledger that was missed).
• Heroes — removing a hero destroys a whole character sheet (skills, traits, conditions, inventory, notes); it was the most destructive delete in the app with no recourse.
• Initiative — removing a combatant, and End encounter, which wipes every combatant's HP and conditions in one tap.
• Treasure — the "−" button silently deleted an item (notes, holder and all) when its quantity hit zero; it now routes through the undo path.

Global search covers Treasure

The Ctrl+K finder indexed quests, people, places, keywords and journal — but not items, so @Sword of… mentions of items silently found nothing. Items are now indexed by name, notes and holder, with their own Item badge.

Keywords get inline editing

The only text ledger where fixing a typo meant delete + re-add (losing the id). Same pencil/Enter/Escape flow as every other panel.

Journal search

The longest-growing list in the app had no filter. It gets the same quick search the keywords list has (shown once more than three entries exist), matching entry text and author.

Realtime sync fix in useGameChannel

A peer's broadcast arriving while a local edit sat in the 400 ms debounce window (or in an unresolved POST) replaced the local view — and the stale local payload then landed on the server anyway. Result: this screen showed the peer's data while the server and every other player ended up with ours, a permanent desync until reload. Peer snapshots are now skipped while a local edit is pending, keeping last-write-wins consistent: the local edit stays visible here and reaches everyone else through the server broadcast once the POST settles.

Smaller fixes

• Underscore emphasis in the Markdown formatter is word-boundary only, so identifiers like cellar_door_key no longer sprout spurious italics.
• The eleven per-panel copies of the uid() helper collapse into one shared makeUid() utility.

Testing

• 14 new tests (undo restore in Journal/Heroes/Treasure/Initiative, keyword inline edit incl. Escape cancel, journal search, Markdown word boundaries, treasure search indexing, and a new useGameChannel spec covering the pending-edit race).
• Full suite: 326 tests green, ESLint clean, production build passes.
