fix: mobile dashboard priority labels now join priorities table

- API: replaced hardcoded wrong map (1=Critical etc) with JOIN on priorities table
- API: sorted by count DESC instead of priority value
- Frontend: PRIORITY_COLOR/TEXT maps updated to cover all 10 actual Autotask values (1-11)
- Middleware: added /api/mobile to publicRoutes (was getting auth-redirected)
