fix: improve combat-happy-path e2e test reliability and speed

- Add data-testid attributes to debug tab buttons (Fill Mana, +10K, +1K, discipline rows)
- Add runTicks(n) to debugBridge for fast-forwarding game ticks in E2E tests
- Fix Step 2: use data-testid selectors instead of fragile DOM traversal for discipline buttons
- Fix Step 4: replace 120s waitForTimeout with runTicks(6000) for deterministic combat
- Fix Step 5: replace 60s waitForTimeout with runTicks(3000)
- Fix Step 6: verify floor decrements after each Climb Down click using waitForFunction
- Fix Step 7: verify Exit Spire button visibility is gated on floor 1
- Remove leftover debug logging (btnInfo DOM inspection)
