fix: promote Huddles back to stable — remove all gating

- Remove huddles entry from features.json (stable = no manifest entry)
- Unwrap FeatureGate wrappers in AppShell.tsx and ChannelMembersBar.tsx
- Remove unused FeatureGate imports
- Remove huddles screenshot test and view-huddles.png
- Remove huddles toggle from 'all on' test (now 4 features)

12/12 E2E tests passing.
