fix: repair persistence - safe-persist getItem now returns parsed objects, fix resetGame localStorage keys

- safe-persist.ts: getItem now calls JSON.parse(str) so Zustand receives {state, version} envelope
- gameActions.ts: fix 5 wrong localStorage keys in createResetGame (mana→mana-storage, etc.)
- Add persistence.test.ts with 12 tests covering round-trip, key verification, and reset
- All 918 tests pass with zero regressions
