Consolidate 5 stat mapper useCallbacks and 6 series useMemos into
single mappers/series objects. Extract statsWhenShown helper for
repeated visibility guard pattern. Deduplicate SSE record envelope
construction. Simplify prepareRecords with if/else. Remove unused
gridColumns ternary with Number() indexing.
Replace all ternary operators with if/else, &&/||, or early returns.
Remove unused noAnimation constant that caused lint error.
Fix variable shadowing in tooltip deduplication loop.
- Surface subscription errors in useLiveStats via onError + error state
- Show error UI in live mode when SSE connection fails
- Abort SSE reader on subscribeTopic failure instead of silent log
- Guard mock realtime against pre-aborted signal to prevent interval leak
- Remove dead includeDocker from subscription input schema
- Skip toReversed() for live data (already chronological from buffer)
- Reset live buffer on systemId/integration change to avoid stale data
- Throw on unexpected SSE stream end so subscription emits error
- Delete unused time-period.ts config (duplicate of server-side config)
- Add subscribeSystemStats tRPC subscription bridging PocketBase SSE
- Add subscribeRealtimeMetrics to BeszelIntegration with SSE parsing
- Add error handling: try/catch in subscription, response check in topic POST
- Add cacheDurationForInput to request handler for per-period cache TTL
- Add mock subscribeRealtimeMetrics with 1s interval for dev testing
