ci: split CI by area with path filters and speed up releases

- ci.yml becomes ci-api, ci-contract, ci-recommender, ci-ts, ci-mobile and
  docker workflows, each filtered by paths; docs-only commits run nothing
- docker builds all four images in one job with plain docker build on the
  runner host, so the layer cache survives between runs
- release no longer re-runs the test suite (the tagged commit already passed
  CI on main); version and release notes are one job
- the android job mounts persistent Gradle and Android SDK caches from
  /opt/ci-cache (when the runner allows the volumes) and uses --build-cache
- RELEASE_TOKEN is optional: fall back to the built-in job token
- docs: CI layout and act_runner settings (capacity, cache, valid_volumes)
