refactor(dashboard): use getEnabledAppIds on metrics page (#1394)

## Summary
Uses the shared `getEnabledAppIds` helper from `@/lib/apps-utils`
instead of manually filtering installed apps with `typedEntries` on the
project metrics page.

## Why
Keeps enabled-app logic consistent with other dashboard code paths and
slightly reduces duplication.

## Test plan
- [ ] Smoke: open project metrics / overview and confirm installed
app-dependent UI (e.g. analytics) still behaves as before.
