Improve test coverage to 87% and point vendor/aprs submodule at codeberg

Coverage:
- Adds focused tests across 13 files covering previously-uncovered
  branches: Packet changeset normalisation (course, wind_direction,
  struct data_extended); Packets store_packet edge cases (nested
  position shapes, ssid handling, string-keyed raw_packet);
  DeviceIdentification HTTP success/404 via Req plug stub; ResendAdapter
  catch-all body, deliver_many, nil/binary formatters; ApiDocsLive
  packets with missing fields; AprsSymbol normalize helpers;
  BadPacketsLive refresh and postgres_notify; MobileChannel handle_info
  catch-all and postgres_packet path; PacketProcessor existing-marker
  movement detection; PacketReplay sanitize_value type clauses;
  InsertOptimizer GenServer lifecycle and negative-duration metric;
  PageController shutdown-handler integration; UrlParams delegated
  helpers.
- mix.exs: configure test_coverage with summary threshold of 87 and
  ignore_modules for test fixtures and macro-only template modules.

Bug fix:
- MapLive.Index handle_info: add a clause for the raw {:new_deployment,
  _} tuple. Phoenix.PubSub.broadcast delivers the raw payload to plain
  subscribers, but the existing handler only matched the %Broadcast{}
  fast-lane wrapper. DeploymentNotifier broadcasts via the raw path,
  which crashed the LiveView under test concurrency.

Submodule:
- Update .gitmodules vendor/aprs URL from
  https://github.com/aprsme/aprs.git to
  ssh://git@codeberg.org/gmcintire/aprs.git.
