test: push line coverage from 71.7% → 78.67%
Adds ~600 new test cases (2013 → 2613 tests; 170 properties; 0
failures) across 12 new test files plus expansions of eight existing
files. Big lifts per module:

  ContactLive.Mechanism      33 → 100%
  MetricsPlug                54 → ~100%
  Microwaveprop.Release      15.8 → 70%+
  Telemetry                  38 → 76%
  HrrrNativeGridWorker       27.7 → 76%
  ContactLive.Show           34 → 48% (handler + render branches)
  Admin.ContactEditLive      49.7 → 70%+
  GefsFetchWorker            35.8 → ~55%
  IonosphereFetchWorker      56.3 → 75%
  PathLive                   58.9 → 67%
  WeatherMapLive             66.9 → 80.2%
  RoverLive                  0 → 70.3%
  ContactMapLive             59.2 → 89.8%
  ContactMapController       0 → 100%
  Mix tasks (Rust.Golden, Notebook, Backtest, HrrrBackfill,
    HrrrClimatology, HrrrNativeBackfill, NexradBackfill,
    RadarBackfill, ImportContestLogs, PropagationGrid,
    ResetEnrichment, Hrrr.PurgeGridPoints)  0 → ~60-100%

Two incidental fixes made while adding tests:

- ContactLive.Show.handle_event("toggle_flag", ...) was passing
  socket.assigns.current_scope to admin?/1 instead of socket.assigns,
  so admins never matched the pattern and every toggle ran the
  "Admins only." flash branch. Flag now toggles for admins again.

- Commercial.PollWorker.fetch_weather/1 promoted from private to
  @doc'd public so the IEM-fetch + ASOS-upsert path can be tested
  directly without driving perform/1 through live SNMP (which was
  timing out for ~50 s per test in the earlier attempt).

Stable property-test additions cover the dewpoint-from-RH monotonicity,
nearest_run/1 idempotence, and the ionosphere station envelope.
