Fastlane metadata format for F-Droid releases (#2501)

* add f-droid metadata support

* share version code calculation with website

* preserve blockquoted sections in changelogs

* refactor(android): simplify stable F-Droid metadata

Generate store changelogs only for stable releases and keep native version-code ownership in the existing release module.

* test(android): run F-Droid changelog suite in CI
