Enhance ticket management with dashboard actions and priority settings

- Introduced a new `runTicketDashboardActionJob` to handle ticket actions (close, claim, set priority) with Discord side effects.
- Added a priority dropdown in the ticket control panel, allowing users to set ticket urgency levels.
- Updated WebUI to display open tickets with options to claim, close, or adjust priority, enhancing user interaction.
- Improved localization for new ticket management features in both English and German.
- Documented changes in phase tracking to reflect the new ticket dashboard functionalities.
