fix(web): suppress HEAD request logs
The log_level(%{method: \"HEAD\"}) clause never matched because
Plug.Head rewrites the method to \"GET\" before Plug.Telemetry's
register_before_send callback fires, so by log time conn.method is
\"GET\". Stash the original method in private before Plug.Head runs
and key the filter off it.

chore(logs): suppress Phoenix Sent log for /live liveness probe
/live fires every 10s per pod; the request line and Sent 200 response
from Plug.Telemetry drowned out real requests. log_level/1 now returns
false for /live too, same treatment /health already got.

fix(logging): suppress /metrics logs and harden scorer hot path
- endpoint.ex log_level/1 now filters by conn.request_path instead of
  conn.path_info. Plug.Router.forward/2 (deps/plug/lib/plug.ex:170)
  rewrites path_info to the unmatched remainder and extends script_name
  with the matched prefix before dispatching to the forwarded plug.
  /metrics is routed via forward "/metrics", MetricsPlug; by the time
  Plug.Telemetry's before_send callback fires inside MetricsPlug.call/2
  the conn it observes has path_info: [] and script_name: ["metrics"],
  so the old log_level(%{path_info: ["metrics" | _]}) clause never
  matched and the default :info level fired. request_path is set by
  the adapter at entry and is never rewritten, making it the correct
  discriminator. New regression test in metrics_log_suppression_test.exs
  captures both the direct shape and the integration path via Plug.Test.

- Scorer.dbz_to_rain_rate_mmhr/1 now uses a compile-time @mp_inv_b
  constant (1 / 1.6) instead of dividing on every rain pixel.
  composite_score/2's band-invariant fallback switched from four
  separate  short-circuits (which silently
  mixed cached and freshly-computed values if only some keys were
  passed) to a single Map.has_key?/2 branch that honors the "all or
  none" contract. Dropped unused band_invariant_tod/1 helper.

- Propagation.replace_scores span scope tightened: the
  Instrument.span([:db, :replace_scores]) now wraps only the per-band
  ScoresFile.write! loop, not the upstream Enum.group_by grouping
  phase. The span name + metadata stay unchanged so Grafana panels
  keep working, but the fixed telemetry dispatch cost (~100µs x 2)
  is no longer paid for trivially small result sets.

- Added @type t :: %__MODULE__{...} to Accounts.UserToken and
  Weather.HrrrClimatology — the last two schemas that lacked one.
  Elixir 1.19's set-theoretic inference benefits from every struct
  having an explicit t/0 so callers can flow through tightly.
