feat(inbox): error tracking source, LLM evaluations, source config improvements

- Add error tracking as signal source with 3 sub-types toggled together
- Replace non-functional LLM analytics toggle with evaluations list (polls 5s)
- Evaluations link to Cloud for management (region-aware)
- Fix re-render cascade: direct API calls, per-source optimistic state
- Per-source onToggle API with memoized cards
- Rounded toggle cards, GitHub OAuth flow
- Add suggested reviewer + artefact types
