fix: b-table filter can't handle filter on 50k element

[1yam]

Jira Ticket

ALEPH-733

---

Issue

When loading around 50,000 addresses in the browser (App.vue#L204),
the b-table component becomes unresponsive and severely impacts performance.

---

Fix Proposed

1. Added debounce (750 ms) on the search input to reduce unnecessary re-renders.
2. Removed b-table’s built-in filtering (too heavy on large datasets).
3. Implemented custom filtering logic in our code to handle it more efficiently.

---

The best solutions:

Implement pagination and server-side search on the API endpoints
so the frontend doesn’t need to load and process tens of thousands of entries at once.
