feat: implement project ignore list for Jira synchronization

- Updated `JiraConfigForm` to include an input for ignored projects, allowing users to specify projects to exclude from synchronization.
- Enhanced `JiraService` with a method to filter out tasks from ignored projects, improving task management.
- Modified user preferences to store ignored projects, ensuring persistence across sessions.
- Updated API routes to handle ignored projects in configuration, enhancing overall functionality.
- Marked the corresponding task as complete in TODO.md.
