Wire up Microwaveprop.AprsRepo as an optional secondary Ecto repo that points at the sister aprs.me Postgres for read-only access. This is the foundation for upcoming 144 MHz calibration work that uses verified APRS RF hops as ground truth. * lib/microwaveprop/aprs_repo.ex declares a read_only repo; no schemas, no migrations, no writes — Microwaveprop never persists APRS data. * Application supervisor starts the repo only when configured (dev/test via config blocks, prod via APRS_DATABASE_URL). A missing config logs a warning and skips startup so the main app still boots. * config/dev.exs + config/test.exs add local aprsme_dev / aprsme_test endpoints. Test pool uses Ecto SQL Sandbox; tests that don't touch APRS data don't need to check the connection out. * config/runtime.exs guards the prod block on APRS_DATABASE_URL — unset env logs a warning and leaves the repo unconfigured.
