Partnership/gitea_ssh_setup.sh: generates ed25519 keypair, registers public key
with Gitea API (POST /api/v1/user/keys), tests SSH connection, writes ~/.ssh/config
entry. Idempotent — skips steps already done. --force regenerates and re-registers.
Resolves Gitea endpoint from container IP first, falls back to GITEA_DOMAIN.
common.sh: alias HOST*_GITEA_API_TOKEN → GITEA_API_TOKEN in detect_hosts().
Add to detect_hosts() doc comment.
master.conf: add GITEA_HTTP_PORT=3000 for API endpoint construction.
host1.conf: add HOST1_GITEA_API_TOKEN (fill in from Gitea Settings → Applications).
Add my-Gitea.xml to HOST1_PARTNERSHIP_AUTH_STACK — onboard pushes it to HOST2.
host2.conf: add Gitea to FALLBACK_HOST2_COVERS_HOST1_TIER1 — starts immediately
when HOST1 goes down, making the source of truth reachable independently of
HOST1's auth stack.
