fix(security,perf): address 9 audit findings (access control, DoS, crashes)
- Beacon detail endpoints (LiveView + REST API) now hide unapproved
  beacons from anonymous and unauthorized viewers; only the submitter
  and admins can see pending records before approval. Adds
  Beacons.get_visible_beacon/2 with scope-aware checks.
- API contact pagination now honors per_page end-to-end.
  Radio.list_contacts/1 accepts :per_page and clamps to 200.
- API rate limiter: ETS table is now owned by a long-lived Sweeper
  GenServer (won't die with a request task); Sweeper periodically
  prunes expired-window rows to bound memory; init_table/0 race is
  rescued.
- /scores/cells and /weather/cells: add per-IP rate limiting and a
  shared GridBounds clamp/413 guard so global / oversized viewports
  no longer drive unbounded binary responses.
- NEXRAD PNG unfilter (sub/up/average/paeth): replace acc++[byte]
  + Enum.at(acc, idx-bpp) with O(n) binary recursion. Decode time
  for the 12200x5400 n0q frame goes from quadratic to linear.
- LiveTableFooter.parse_page and ScoresFile.fetch_bound: switch
  String.to_integer/String.to_float to Integer.parse/Float.parse,
  fall back to defaults instead of raising.
- PathLive and MapLive band-event handlers: replace
  String.to_integer(params["band"]) with parse_int / parse_band_param
  so a non-numeric band parameter no longer crashes the LiveView.

fix: April 2026 codebase review — address 13 bugs across propagation chain
Each fix is covered by a regression test that fails on `main` and
passes on this commit.

Round 1 (initial review):

* propagation: thread `latitude` into the conditions map so
  `score_season/4` actually picks up regional multipliers
* hrrr_client / fetcher.rs: `nearest_hrrr_hour` rounds DOWN, never at
  a future cycle that NOAA hasn't published yet
* radio: spherical-vector great-circle midpoint replaces the
  arithmetic mean — anti-meridian paths no longer fold to Greenwich
* weather: `reconcile_weather_statuses` scales the longitude band by
  `1 / cos(lat)` so the bbox stays ~150 km wide at every latitude
* radio/maidenhead: clamp 90°/180° below the field-bucket overflow so
  `from_latlon` never emits invalid characters like 'S'
* prop_grid_rs/pipeline: merge HRRR + NEXRAD-derived rain rates and
  read `best_duct_freq_ghz` into `best_duct_band_ghz` so the Native
  Duct Boost actually fires
* propagation/region (Elixir + Rust): inclusive upper bounds so points
  exactly at lat_max get the regional multiplier
* weather/sounding_params (Elixir + Rust): drop the 10 m gradient
  floor so HRRR's thin near-surface layers stop hiding sharp ducts
* weather/sounding_params: when the profile ends inside a duct,
  finalize it with the highest sample as the top instead of throwing
  it away (Rust port already correct)

Round 2 (post-fix sweep):

* radio + commercial: single canonical haversine in Radio (atan2
  form); Commercial delegates instead of carrying a second copy that
  could disagree at threshold distances
* prop_grid_rs/profiles_file: `snap_coords` matches Elixir's
  step-aware snap (`round(coord/0.125) * 0.125`, then 3-dp round) so
  Rust-keyed and Elixir-keyed profile maps land on the same cell
* weather/grib2/wgrib2: `parse_lon_val_segment` uses `Float.parse`
  uniformly — wgrib2 dropping the trailing `.0` from a longitude no
  longer crashes the whole chain step
