fix: new CI deploy key + plane-api longer startup timeout

- Rotate ci_deploy_pubkey to new ed25519 key (old key lost after
  server rebuild; Forgejo secret SSH_PRIVATE_KEY updated to match)
- Increase plane-api start_period 60s→120s, retries 5→10 to give
  Django time to run DB migrations after backup restore
