Pin platform 0.1.0 release and wire up automatic propagation

- parent/BOM now point at the immutable 0.1.0 release instead of a SNAPSHOT
- declare the Gitea Maven registry so Renovate can discover new platform versions
- renovate.json: group platform bumps into one automerged PR
- CI: drop --no-cache (releases are immutable, so caching is safe again) and add
  workflow_dispatch so rebuild-all-apps.sh can force an urgent rebuild
