Subject: [PATCH] fix: fork under own applicationId
 com.rtbishop.look4sat.bg7nta

The official app signs com.rtbishop.look4sat with its own certificate. A fork sharing that applicationId cannot be installed over the official build (signature mismatch) and users saw overwrite/install failures.

- Add applicationId version catalog entry; namespace stays com.rtbishop.look4sat so source imports are untouched, applicationId becomes com.rtbishop.look4sat.bg7nta.
- Update PROPERTY_SATELLITE_DATA_OPTIMIZED meta-data to the fork id.
- Document the fork-applicationId requirement in the version catalog.
