Subject: [PATCH] fix(rflood): add liveness probe and raise memory limit to 4Gi

rtorrent periodically freezes blocking Flood's XMLRPC calls (activity-stream
and client/settings hang). Root causes: pieces.memory.max=1800M near the 2Gi
container limit; no liveness probe to trigger pod restart on hang.

- Liveness probe: exec rtxmlrpc system.time_seconds with 10s timeout; restart
  pod after 3 consecutive failures (every 30s check)
- Default memory limit raised from 2Gi to 4Gi
