qbittorrent: bake performance settings into initContainer

Switch qbt-config-patch from busybox/sed to python:3-alpine so we can
cleanly handle INI keys with backslashes. Now seeds both password hash
and high-throughput defaults (3000 max connections, 50 active downloads,
unlimited rate) on fresh PVC deployments. Existing configs are updated
in-place; API-applied values are preserved on restart.
