feat: add workflow to sync secrets to sibling repositories

Adds a manually-triggered workflow that copies secrets from
unity-builder (repo + org level) to target repos like orchestrator
and cli. Uses GIT_PRIVATE_TOKEN for cross-repo API access.

Secrets synced: UNITY_EMAIL, UNITY_PASSWORD, UNITY_SERIAL,
GIT_PRIVATE_TOKEN, LOCALSTACK_AUTH_TOKEN, GOOGLE_SERVICE_ACCOUNT_EMAIL,
GOOGLE_SERVICE_ACCOUNT_KEY, CODECOV_TOKEN.
