fix: update e2e tests for localhost and current game architecture

- playwright.config.ts: change baseURL from dev site to localhost:3000
- combat-happy-path.spec.ts: fix climb button location (LeftPanel, not spire tab), fix descent via store, handle game-over from day overflow, reduce tick counts to avoid day 30 limit
- fabricator-happy-path.spec.ts: set currentAction to meditate before crafting (required by startFabricatorCrafting)
- playtest.spec.ts: rewrite from scratch — use localhost, window.__TEST__ bridge (not window.__debug), current tab names (no grimoire/element tabs), split into 3 files under 400-line limit
  - playtest-basic-ui.spec.ts: sections 1-3 (basic UI, stats, spire)
  - playtest-tabs.spec.ts: sections 4-11 (all tab navigation tests)
  - playtest-debug.spec.ts: sections 12-14 (debug tab, bridge, stress test)
