feat(rflood): switch to jesec/rtorrent-flood to fix scheduler crash

hotio/rflood bundles rtorrent with a scheduler assertion bug that fires
on torrent delete and shutdown. jesec/rtorrent-flood uses an actively
maintained rtorrent fork with this fixed.

Changes:
- Image: hotio/rflood → jesec/rtorrent-flood:4.14.2
- webuiPort: 3000 → 3001
- Add ConfigMap for .rtorrent.rc (jesec requires explicit config)
- Replace PUID/PGID env vars with pod securityContext (runAsUser/Group 1001)
- Liveness probe: exec rtxmlrpc → httpGet on webui port
- Remove TCP RPC port from service (jesec uses Unix socket)
- Update version-source to dockerhub-tags-pattern for jesec tags
