Two new entries in the existing GPS section of SettingsScreen, gated by
the same ENV_INCLUDE_GPS guard. LEFT/RIGHT cycles through the option
table from Trail.h:
- "Trail int" : 30 s / 10 s / 20 s / 1 min / 5 min / 15 min
- "Trail dist": 5 m / 10 m / 25 m / 100 m

Changes are stored to p->trail_interval_idx / trail_min_delta_idx and
take effect on the next sampling tick in UITask::loop (already gated on
those fields), so no separate apply* helper is needed. _dirty triggers
the normal savePrefs on settings exit.
