fix: bake Woodpecker OAuth2 + agent secret into Helm values

Permanent fix for cluster rebuilds:
- OAuth2 client_id/secret baked into woodpecker/values.yaml
- WOODPECKER_AGENT_SECRET shared between server and agents
- runmefirst.sh uses baked creds if present, creates fresh ones only
  if values.yaml still has placeholders
- Agents survive DB wipes since they auth via shared secret
