## Summary
Adds route analytics heatmaps, stacked on top of
`codex/analytics-overview-filters` (#1496).
- Heatmap API routes (`/analytics/heatmap`, internal heatmap +
heatmap-token endpoints)
- Signed heatmap token signing/verification lib + tests
- Dashboard heatmaps page (client + route)
- Dev-tool + event-tracker support for heatmap capture
- ClickHouse migration support

## Notes
Base branch is `codex/analytics-overview-filters` so the diff shows only
the heatmap changes. Will retarget to `dev` once the base PR lands.

* Browser-side event tracker with batching, navigation & click capture
and background/keepalive delivery
* Server endpoint to accept batched analytics events and associate them
with session replay segments
* Client APIs to send analytics batches and integrate with session
replay

* Pausing replay now uses the UI-facing playback time for more accurate
pause positions
* Replay endpoint now returns a clear analytics-disabled error
(ANALYTICS_NOT_ENABLED) when analytics is off
* **Tests**
* End-to-end tests covering batch ingestion, validation, and replay
timing behavior
