Rename the Gitea repo references to ProLibertateGames

The repo was renamed from PilgrimsOfKatan to ProLibertateGames on the
Gitea instance. Update every reference so nothing points at the old name:

- OTA updater: the repo constant and the User-Agent
- publish-release.sh: the default repo, the asset name, the release title
- CI/release workflows: the artifact names and the staged APK name
- settings.gradle.kts: the Gradle project name
- Protocol.kt / LanTransport.kt: the mDNS service label and the Wi-Fi lock tag
- docs (README, CLAUDE.md, docs/CI.md) and the update-policy test fixtures

The installed applicationId is left unchanged in this commit.

 what publishing requires. Setting the flag to `false` is the kill switch.
