Tavern Board - whole-roster party listings

Publishing now posts your entire guild roster as one grouped party listing instead of one character at a time. Other players can hire the whole party for a raid, or pull individual members into a dungeon party.
The Tavern Board's "Players" browse section now server-side samples real player listings (rate-limited, capped) instead of an unbounded fetch that got slower as more players posted.
Accounts with leftover per-character listings from the old model are recovered automatically, once.

Login/session fixes

Fixed a flash of the sign-in/create-account screen for already-logged-in returning players, caused by a race between local-save loading and auth-session restoration.
An involuntary session drop (idle refresh-token expiry, cross-tab sign-out) now flushes and mirrors your save before falling back to the logged-out view, instead of risking a save that looks like lost progress.
Offline-progress correctness (4 bugs fixed)

Raid parties containing hired guildmates or Tavern mercs would clear once during an offline session and then sit idle for the rest of it instead of continuing to farm.
Any raid — including bot-only parties — already sitting on its victory/wipe screen at the moment an offline session began never resumed at all, for the whole gap.
The Tavern Board's daily assist-token cap was keying off the real calendar date instead of simulated offline time, silently capping multi-day-offline lenders at one day's rewards.
Dying in a dungeon (solo or full party wipe) never auto-retried, live or offline — fixed to auto-retry once death fatigue clears (~60s), with a visible countdown on the wipe screen.

Infrastructure

Two Supabase migrations applied to production for the party-listing feature (backward-compatible with any not-yet-updated client).
