fix: PBS namespace selector, LXC IP fallback, docs v0.9.6

- PBS namespace dropdown now wired up — passes ns param to snapshots/groups API (#301)
- LXC IP fetch: fallback to /config static IP when /interfaces returns empty (#300)
- Docs updated to v0.9.6 with Predictive LB, ISO Sync, Push Notifications sections
- Docs changelog for v0.9.6
