Custom migration targets - Persist filter state

[sjd78]

On the custom migration targets page, persist the filter state so the filter state is retained when navigating around the app. Persistence can be in session or URL params.

Current behavior:

Screencast.From.2025-04-28.14-02-34.mp4

On navigation back to the page, it would be good to retain the filters.
