feat(trail): auto-save GPS trail on shutdown (Trail settings toggle)

Browse Source 
Losing the whole route on a low-battery auto-shutdown was the worst solo-mode
failure. New NodePrefs::trail_autosave_lowbatt toggle (Tools > Trail >
Settings > Auto-save, default OFF): UITask::shutdown() writes the live trail
to /trail when the toggle is on and _trail.count() > 0. The count guard stops
an empty trail from wiping a previously saved one; it overwrites the same
/trail file the manual Trail > Save uses.

Schema bumped 0xC0DE001A -> 0xC0DE001B: append-only tail field with a load
clamp, so pre-0x1B saves default to off. sizeof(NodePrefs) is unchanged (the
byte fits existing padding after keyboard_type), so the tripwire assert stays
2496.

Builds green: WioTrackerL1_companion_solo_dual (RAM 69.9%, Flash 62.8%).
