chore(sentry): filter NS_ERROR_UNEXPECTED + ConvexError API_ACCESS_REQUIRED (#3188)

NS_ERROR_UNEXPECTED (WORLDMONITOR-N6/N7/N8/N9): Firefox 149/Ubuntu XPCOM
Worker init failure. Same family as already-filtered NS_ERROR_ABORT and
NS_ERROR_OUT_OF_MEMORY. 0 repo matches. Worker fallback confirmed working
via breadcrumbs ("keeping flat list").

ConvexError: API_ACCESS_REQUIRED (WORLDMONITOR-NA, 15 events/5 users):
expected business error from PR #3125 (API key management). Free user opens
API Keys tab, server correctly denies, client try/catch at
UnifiedSettings.ts:731 handles gracefully. Convex WS transport leaks the
rejection to Sentry before the client Promise chain catches it.
