feat: add projectId support to service mutations

- Add projectId field to schema for serviceDelete, serviceUnsetSecret,
  UpdateServiceInput, SetSecretsInput, DeleteSecretsInput
- Add projectId to FindService query response
- Update DeleteService and UnsetSecret callers for new signature
- Regenerate genqlient types

Currently passes nil for projectId (uses slug fallback). The backend
prefers projectId when provided but falls back to workspace+slug lookup.
