UI overhaul "Living Codex" E: per-screen layouts

Ported all 9 screens to the prototype layout (visual only; all data wiring, text,
aria-labels, and testids preserved) via parallel agents + central verification:
- Dashboard: editorial hero, party roster w/ HP meters + avatars, quests, threats, rolls.
- Campaigns: cover-art deck cards + gilt rule + footer.
- Character sheet + roster: hero header, StatCoin abilities, prof rows; grimoire cards.
- Combat: glowing initiative rows (PC gilt / foe ember), condition badges, log.
- Dice: die-pool glyphs, adv/dis segmented toggle, crit/fumble stage, history.
- Compendium: Spectral stat blocks (ember headers, ability row).
- Settings: grouped icon-tile cards. Live Session: room-code card, seat grid, player board.
- Battle Map: carded list + tooled editor chrome (canvas untouched).

Regression fixes after the ports: dice die-buttons aria-label `d4` not `Roll 1d4`
(was colliding with the primary Roll button); map "Open player view" link uses an
ExternalLink icon (test updated, ↗ glyph removed); seat-claim card gets a stable
data-testid="seat-option" (redesign moved rounded-lg→rounded-xl).

223 unit + 34 e2e + 2 realtime green; tsc + eslint + build clean.
