* fix(dashboard): cache org stats in Redis with versioned invalidation
Replace the never-expiring process-local cache in the org dashboard page
load with API-side Redis caching keyed per org. A version stamp prevents
slow reads from writing pre-purge data back into the cache.
Invalidate on course create/update/delete, student enroll/remove, certificate
claim, and progress reset. Remove the dashboard SSR module cache so every
page load reads through the API cache layer.
Fixes#852

* fix(dashboard): address PR review on stats cache invalidation
- Validate bust via ZDashStats instead of raw query access
- Use import type for OrganisationAnalytics
- Resolve orgId before course delete so invalidation is reliable
- Invalidate immediately after persisted writes, before fallible side effects
- Invalidate on member role changes and program course access enrollment

* fix(dashboard): complete stats cache invalidation coverage
Wire org stats cache purge on lesson completion (manual toggle and
video-watch auto-complete) so topCourses completion percentages stay
fresh. Harden bulk member adds with sequential inserts and a finally
invalidation boundary, and only purge org invite enrollments when new
group memberships were actually inserted.

* fix(core): make lesson completion stats purge best-effort
Wrap org stats cache invalidation in try/catch so a lookup or Redis
failure cannot turn a successful lesson completion into a 500.

* fix(dashboard): keep org stats cache through lesson completion
Lesson complete is a high-frequency event and usually does not change
the rounded dashboard percentages. Rely on a 10 minute TTL instead of
purging the snapshot on every completion.

* docs: explain how admin dashboard numbers are calculated
Add a user-facing guide covering headline counts, top courses,
certificates, login activity, and when the 10 minute snapshot refreshes.
