Fix My Tickets and queue filter

- My Tickets: exclude RESOLVED and CLOSED, show active tickets only
- Queue filter: cascading Category > Type > Item picker — each leaf is
  a distinct queue (e.g. TheWrightServer > Automation > Backup vs Sync)
- Server: support typeId and itemId as ticket list filter params
