feat(ui): GPS fix icon on status bar, minimap distance label, hide Tools icons

- Status bar: add a boxed/plain GPS reticle icon reflecting LocationProvider
  fix state, shown only on boards that have a location provider. Drop the
  now-redundant "Fix:y/n" text from the map page's info line.
- Home minimap: replace the bottom-left scale bar with a "->dist" label to
  the nearest live-tracked point when one is available, falling back to a
  smaller single-tick scale indicator otherwise. Less likely to be covered
  by a plotted point than the old full-width bar, and more useful at a
  glance. Drop the now-duplicate nearest-distance text from the map page's
  info line.
- Tools screen: comment out per-row/section icons (kept for easy restore) —
  they don't fit visually in that list for now.
