fix: release v0.2.1 lesson deletes and large uploads

- Raise Traefik read timeout to 1h (compose dev/prod + k3s HelmChartConfig)
  so admin video uploads up to 200MB no longer 502 mid-upload.
- Migration 0029: cascade watch/quiz history on lesson delete and unlink
  dependent lessons, so removing a lesson or chapter stops 500ing.
- Add the Apollo cluster Helm overlay (values-apollo.yaml) for the deployed
  environment.
- k3s Traefik chart config also enables access logs, cross-namespace
  IngressRoutes, and fixes the Prometheus scrape port.

Bump appVersion/product.go/values tags to 0.2.1; chart version 0.2.3.
