v1.51.0: explicit hide flags, the yellow principle, phone editor gestures, room button

The dev batch since v1.50.4, released as one:
- hiding is a per-device checkbox seeded once from the old filter
  (docs/FILTERING.md); blue ghosts under a local 'Show hidden' toggle
- yellow = doing its main job now; TRVs glow by hvac_action, service
  switches can no longer become a device's primary
- pinch/pan gestures in every editor on touch
- the room settings button: visual centre (inscribed circle + centroid
  pull), icon-derived size, zooms with the plan; metrics visible in the
  plan editor

Inventory: 147 frontend / 51 pure / 43 harness / 68 smokes.
