feat: debug panel with force unlocks and hard reset (#65)

## Summary
- Adds a new **Debug** tab to the game UI with two self-service tools for players with broken save state
- **Force Unlocks**: scans the player's save and grants any zones, quests, bosses, and exploration areas they've earned but that are still locked — shows a breakdown of what was unlocked (or reports nothing needed fixing)
- **Hard Reset**: wipes progress back to a fresh save (preserving lifetime stats), guarded behind a confirmation modal to prevent accidental clicks

## Files added
- `apps/api/src/routes/debug.ts` — two POST endpoints (`/force-unlocks`, `/hard-reset`)
- `apps/web/src/components/game/debugPanel.tsx` — the Debug tab UI
- `apps/web/src/components/ui/confirmationModal.tsx` — reusable confirmation modal

## Files modified
- `apps/api/src/index.ts` — registers the debug router
- `packages/types/src/interfaces/api.ts` — adds `ForceUnlocksResponse` type
- `packages/types/src/index.ts` — exports the new type
- `apps/web/src/api/client.ts` — adds `forceUnlocks()` and `debugHardReset()` API calls
- `apps/web/src/context/gameContext.tsx` — wires both functions into game context
- `apps/web/src/components/game/gameLayout.tsx` — adds the Debug tab
- `apps/web/src/styles.css` — styles for action buttons, cards, result messages, and confirmation modal
