Bug/CLARK-CLIENT-18/fix-typeerror-filter

[sentry]

This PR addresses CLARK-CLIENT-18, a TypeError: Cannot read properties of undefined (reading 'filter') occurring in /onion/dashboard/.

Root Cause:
The getReleasedLearningObjects method in dashboard.component.ts was calling this.checkQueryParams$.next() synchronously before the asynchronous API call (this.searchService.getUsersLearningObjects) had completed and assigned data to this.releasedLearningObjects. This created a race condition where the route params subscription, triggered by checkQueryParams$, would attempt to call .filter on an undefined this.releasedLearningObjects.

Solution:
To resolve this, the this.checkQueryParams$.next() call has been moved inside the .then() callback of the getUsersLearningObjects promise. Additionally, await was added to the promise chain to ensure the execution pauses until the promise resolves. This guarantees that this.releasedLearningObjects is populated before checkQueryParams$ emits, preventing the TypeError.

Fixes CLARK-CLIENT-18
