refactor(ui): rename "Breadcrumb" to "Trail" across the feature

Browse Source 
User-facing label change requested for the GPS trail viewer. Carries
through internally for consistency:
- Files: Breadcrumb.h → Trail.h, BreadcrumbScreen.h → TrailScreen.h
- Types: BreadcrumbPoint/Store/Screen → Trail*
- NodePrefs fields: breadcrumb_*_idx → trail_*_idx (same byte layout, no
  sentinel bump needed)
- UITask: _breadcrumb, breadcrumb_screen, gotoBreadcrumbScreen,
  _next_breadcrumb_sample_ms → trail-prefixed equivalents
- Tools menu label "Breadcrumb" → "Trail", screen title "TRAIL"

Status bar indicator stays "G" — semantics ("GPS logging active") match.
