Paints carry search or track; a ping sweep warns every ship it crosses in its beam; allies hear the return silently

Browse source 
LockWarning becomes PaintWarning with a PaintMode (Search for a ping sweep, Track for a lock);
Entity.IncomingLocks becomes IncomingPaints. Sensor replaces the _pingedEntities set with a stateless
crossing rule over the previous and current wavefront radius, limited to a new BeamWidth stat (key 12,
absent reads 360), and credits allied pings from the receiving sensor's own sensitivity and distance.
The HUD lock indicator follows Track paints only. Folds in the radiator sampling-instant pin.

Unverified at this commit (first build still to run).
