## Context
Previous PR was [here](https://github.com/supabase/supabase/pull/45143)
but it got stale with lots of conflicts so figured it'll be easier redo
it off the latest master
Moves policies page from Auth to Database under an Access Control
section along with Roles. This moves all existing files, applies
redirects, and updates urls to point to the new route

Closes#45847.
## Summary
`ProjectNeedsSecuringView.tsx` built the `View policies` href on the
first-time security gate by interpolating `table.schema` and
`table.name` directly into the URL. A table or schema containing `&`,
`=`, `+`, or `#` corrupted the destination and routed the user to the
wrong policies filter on what is meant to be a guided onboarding flow.
Extracts the URL into `getTablePoliciesHref` in
`ProjectNeedsSecuring.utils.ts` with `encodeURIComponent` wraps, and
replaces the inline interpolation. Same pattern as #45385.
## Test plan
Added `ProjectNeedsSecuring.utils.test.ts` covering
`getTablePoliciesHref` (plain values, special chars in name, special
chars in schema, both, undefined inputs) and pulling in the
previously-untested `getTableKey`, `formatRlsDescription`, `sortTables`,
and `buildSecurityPromptMarkdown` utilities. Ten tests total.
