feat(rover-planning): worker pre-computes full /path output, PathLive renders cached
Three connected changes:

1) Extract PathLive.compute_path/4 + every helper it owned (resolve,
   profile grid lookup, sounding/ionosphere readouts, scoring, loss /
   power budgets) into Microwaveprop.Propagation.PathCompute. PathLive
   now delegates; ~410 lines of dead helpers deleted from PathLive.

2) RoverPathProfileWorker calls PathCompute.compute/4 with the
   mission's heights and PathLive's default station params (10 W TX,
   30 dBi gains). Stores the full atom-keyed compute output as a
   Base64-encoded :erlang.term_to_binary/1 blob alongside the flat
   summary fields the rover-planning show table reads. The blob
   roundtrips structs and DateTime exactly (Jason.encode would lose
   them).

3) PathLive accepts ?rover_path_id=UUID. When set, loads the cached
   Path, decodes the term (binary_to_term :safe), assigns it as
   @result, and renders normally — no compute_path call. The
   rover-planning show table now links rows directly to
   /path?rover_path_id=UUID, so a click opens the full Path
   Calculator UI from cached data without re-running terrain / HRRR /
   sounding lookups.

Bonus prod fixes folded in:
- PathShow's elevation chart attribute (data-* → data-profile JSON)
  was crashing the JS hook with 'unexpected character at line 1'.
- Station.changeset now wipes previously-resolved callsign/grid/
  lat/lon when the user types into :input — typing 'AA5' early
  resolved to a wrong location and locked it; subsequent keystrokes
  never re-resolved.
- phx-debounce=600 on the station input so QRZ doesn't get hit on
  every keystroke.
