chore: add proprietary license (All Rights Reserved)

- Add whitelist of valid actions to prevent arbitrary action values
- Fix error handling to properly detect database failures

Previously, any action value was accepted without validation, which could lead to unexpected behavior. The health check also incorrectly set dbOK to true when queries succeeded, now correctly sets it to false when errors occur.
