fix(myorg-assistant): normalize GIT_REPO_URL host to git.rogi.casa in git-sync

PR #26 added the git-clone initContainer but still trusted the GIT_REPO_URL
secret verbatim. That secret historically contains gitea.rogi.casa, which
526s through Cloudflare, so the clone still fails with 'Not a git repository'.

Normalize the host to git.rogi.casa at runtime (sed) so the clone works
regardless of the secret's stale host. Directly addresses the subdomain bug.
