feat(localization): add timer conflict handling and update translations

- Introduced a new hook `useTaskTimerWithConflictCheck` to manage timer conflicts, prompting users when a timer is already running for a different task.
- Updated localization files for Albanian, German, English, Spanish, Portuguese, and Chinese to include new translation keys related to timer conflict handling and cancellation.
- Refactored components to utilize the new timer hook, enhancing user experience by preventing overlapping timers.
