* fix(policies search): replace useUrlState with nuqs
There is a bug when typing quickly into the search field on the policies
page: because useUrlState naively uses router.replace, which is
asynchronous, the search term can get corrupted, e.g., searching for
"dummy" might end up with a final value of "dum". Switched to nuqs for
better handling.
* perf(policies page): memoize and optimize for projects with many tables
A project with hundreds of tables will have extremely slow search
performance for the policies page, because of heavy rerendering. Made
some optimizations:
- Memoized to reduce rerendering
- Hid filtered-out tables instead of unmounting, so we don't have to
remount when the search is cleared
* refactor(policies page): pass policies info through context
Avoid having a mess of props by creating a PoliciesDataContext to share
policy information.
* cleanup(policies pages): minor code cleanup, no user-facing changes
