feat(ui): trail — fixed 1 s sampling; drop GPS upd + Trail int from settings

Browse Source 
GPS NMEA polling is cheap, and a slower cadence just hides motion from
the trail; the min-delta gate already filters jitter without throttling
the GPS. Both knobs that exposed cadence-style controls to the user are
removed:

- Trail sampling is fixed at TrailStore::SAMPLING_SECS = 1 s, matching
  the sensor manager's built-in GPS update default. The
  intervalSecs / intervalLabel / INTERVAL_COUNT helpers go with it.
- GPS update rate ("GPS upd" entry) leaves the sensor manager on its
  built-in 1 s default. applyGPSInterval and the GPS_INTERVAL_OPTS /
  LABELS tables / gpsIntervalIndex helper are deleted.

Both NodePrefs fields (gps_interval, trail_interval_idx) are retained
as reserved so the schema sentinel doesn't have to bump — older saves
load cleanly, the bytes are just ignored.
