refactor: only show critical/warning patrol findings

Filter out 'watch' and 'info' severity findings from the API response.
These lower-severity findings were mostly noise:
- 'watch': CPU is 35% instead of 11% (who cares)
- 'info': Stopped container exists (knew that)

Now only showing actionable findings:
- critical: Something is broken NOW
- warning: Something needs attention soon

Users prefer silence to noise.
