feat: custom poll interval input in dashboard header

- Replace SWR polling with a manual setInterval that responds to interval changes
- Add number input in header (milliseconds) that updates polling in real-time
- Move error state to a single error variable shared by the poll effect
- Remove SWR dependency from Dashboard (still used by API routes for internal fetching)
