Gitea MCP connector: MCP OAuth mode on bikoret.ch

The claude.ai connector ran the OAuth flow against a server in
static-token mode, which has no OAuth endpoints: the login ended on a
404. The proper form is gitea-mcp's -oauth mode, where each user
authorizes with their own Gitea account; it needs both origins public
over HTTPS and Gitea's ROOT_URL to be that origin.

- gitea-ingress.yaml: git.bikoret.ch → temple-council/gitea, TLS
- gitea-public-patch.yaml: ROOT_URL/DOMAIN/SSH_DOMAIN = git.bikoret.ch
  (were a name that never resolved and a released NLB IP)
- gitea-mcp-deployment.yaml: -oauth -oauth-public-url
  https://mcp.bikoret.ch -H https://git.bikoret.ch, no static token,
  probes on /healthz
- gitea-mcp-ingress.yaml: host mcp.bikoret.ch (mcp.shorashim.ch retired)
- gitea-public-apply.sh / gitea-public-verify.sh: the operator's
  DNS-gated apply and read-only verification (also in ~/.local/bin)
- KOHEN.md, deploy/ARCHITECTURE.md: the new doors and the Gitea OAuth2
  app ("Claude", PKCE, claude.ai + Claude Code redirect URIs)
