fix: align error messages with original distrobox format

- Use ERROR: prefix (uppercase) for critical errors matching original
- Change "Failed to create container" to lowercase "failed to create"
- Change "Container Setup Failure!" to "Error: could not start entrypoint"
- Change "Unknown command" to "invalid command"
- Change "Invalid container manager" to "Invalid input" format
- Remove [error] tags in upgrade message, use red() directly
