Fix Docker deployment with Gleam integration

- Update gleam_compile task to handle missing mix_gleam/gleam binary
- Add fallback to use pre-compiled BEAM files from priv/gleam
- Include pre-compiled aprsme@encoding.beam for Docker builds
- Update both Dockerfiles to ensure priv/gleam directory exists
- Fix module name filter from "aprs@" to "aprsme@" in fallback logic

This ensures Docker builds work without requiring gleam or mix_gleam
to be installed in the production container.
