feat: implement Jira auto-sync scheduler and UI configuration

- Added `jiraAutoSync` and `jiraSyncInterval` fields to user preferences for scheduler configuration.
- Created `JiraScheduler` service to manage automatic synchronization with Jira based on user settings.
- Updated API route to handle scheduler actions and configuration updates.
- Introduced `JiraSchedulerConfig` component for user interface to control scheduler settings.
- Enhanced `TODO.md` to reflect completed tasks related to Jira synchronization features.
