refactor: centralize GitHub logic into GitHubService

- Create GitHubService with parseUrl, extractRepo, getBranches, getLatestCommit, getLatestRelease, hasUpdates
- Replace duplicated GitHub parsing in EmulatorConfiguration with GitHubService
- Replace fetchGitHubBranches, extractGitHubRepo, getEmulatorRemoteVersion in Commandocentrum
- Reduce code duplication across services and controllers
