refactor: stabilize calendar loading effects and menubar redirect

- Memoize calendar range strings and stabilize effect deps
- Guard updateDarkColor to avoid dispatch loops
- Add resilient cache-clear handling with refs
- Memoize calendar/temp ids to prevent rerenders
- Update event handler hooks with missing deps
- Add guards and dependency fixes across Calendar effects
