fix(dialyzer): clear 125+ warnings under strict flags
Enabled :error_handling, :unknown, :unmatched_returns, :extra_return,
:missing_return in an earlier commit and landed a 129-warning baseline.
Four parallel agents each fixed a directory slice:

- Core contexts (29): Radio, Release, Weather, Beacons, Cache,
  Backtest.Features, Terrain.Srtm, Ionosphere.GiroClient,
  Propagation.RunTiming, Accounts.Scope, RepoListener. Fixes were
  (a) prefix side-effect calls (Task.start, Phoenix.PubSub,
  Logger, :ets.new) with _ = ; (b) tighten/widen specs that didn't
  match actual returns; (c) add missing @type t declarations;
  (d) drop dead parse_int(nil) clause.

- Propagation + weather subdirs (15): FreshnessMonitor, NotifyListener,
  ScoreCache, ScoreCacheReconciler, Weather.FrontalAnalysis,
  Weather.Grib2.Extractor, Weather.Grib2.Wgrib2, GridCache,
  HrrrPointEnqueuer, NexradCache. Same patterns — mostly _ = on
  PubSub / :ets / Repo.insert_all; widened two specs (float ->
  number) where integer returns were reachable.

- Workers (35): BackfillEnqueue, CanadianSoundingFetch,
  ContactImport, ContactWeatherEnqueue, GefsFetch, IemreFetch,
  NarrFetch, SolarIndex, TerrainProfile, WeatherFetch. Prefixed
  Repo.update_all / Radio.set_enrichment_status! / Weather.upsert_*
  side-effect calls. Fixed one :pattern_match in
  CanadianSoundingFetch.most_recent_sounding_time/1 where a
  tautological cond guard generated unreachable code.

- Web + Mix tasks + lib_ml (46 of 50): controllers, LiveViews,
  UserAuth, and 11 mix tasks. Same prefix strategy. 4 remaining
  warnings originate in LiveTable.LiveResource dep macro expansion
  and can't be fixed without forking the dep — added .dialyzer_ignore.exs
  to suppress just those specific file:line pairs.

Also wired ignore_warnings in mix.exs dialyzer config.

defmodule Mix.Tasks.RadarBackfill do
@shortdoc "Enqueue CommonVolumeRadarWorker for contacts with radar_status :pending"
@moduledoc """
Bulk-enqueue per-contact common-volume radar enrichment for historical
contacts.
Eligible contacts: post-2014-10-02 (outside NARR coverage), both pos1
and pos2 present, `radar_status = :pending`. The worker's own unique
constraint on `contact_id` makes re-runs idempotent.
Options:
--limit N Maximum contacts to enqueue per run (default: all)
--year N Only enqueue contacts from this year (optional filter)
--dry-run Print counts; don't enqueue
Example:
mix radar_backfill --year 2024 --limit 5000
