The live-tail stream (now reachable through the new Vite /api proxy)
started delivering activity rows with kind="manual_match", a kind the
ActivityFeed kindConfig map didn't know about. The map lookup returned
undefined, and reading .icon on it threw — taking the whole Activity
Log page down.
Two fixes:
1. Add "manual_match" to the ActivityKind union in src/types/index.ts
and to the kindConfig map in src/components/ActivityFeed.tsx (with
a Wrench icon + neutral tone), so the kind is properly typed and
rendered.
2. Add a FALLBACK_KIND guard so any future backend-emitted kind that
arrives before the frontend is updated no longer crashes the page.
kindConfig stays exhaustive for known kinds, so TypeScript still
catches missing entries at compile time.
Also adds src/components/ActivityFeed.test.tsx with three regression
tests (empty state, multi-item render, unknown-kind safety).
