There are only two/three polls showing in Polls in Mess Committee Section

**Problem:** Only two or three polls are visible in the **Polls** section of the **Mess Committee** section, even though more polls are expected to be displayed.

**Expected Behavior:** All available polls should be listed in the **Polls** section.

**Steps to Reproduce:**
1. Open the **MessEase** app.
2. Navigate to the **Mess Committee** section.
3. Go to the **Polls** tab.
4. Observe that only two polls are displayed, regardless of the actual number of polls created.

**Possible Causes:**
- Pagination or query limitation in Firestore/Supabase.
- Filtering or visibility issue in the RecyclerView/Adapter.
- Backend not returning all polls.

**Suggested Fixes:**
- Check the query fetching polls to ensure it's retrieving all relevant entries.
- Verify pagination settings and increase the limit if necessary.
- Debug the RecyclerView adapter to confirm if it's correctly binding all received data.

### Concerned Files:
`PollsFragment.kt`
`PollAdapter.kt`
`PollsViewModel.kt`

Start by reproducing the issue in the MessEase app and trace the poll-loading flow through PollsFragment.kt, PollAdapter.kt, and PollsViewModel.kt. Check whether all available polls are returned and bound, then verify in the Polls tab that the complete poll list is displayed.
