## Context
This is one chonky boy of a PR, but it's just re-organizing files and
folders to clean things up
Storage Policies have been using the old Database policy UI (the one
with the Dialog), so it makes most sense to shift those files under the
`Storage` folder instead of keeping them under `Database`, so it's
clearer which files are being consumed by whom, and easier to clean
things up as well
As part of this clean up, also tore out all the RLS generation logic
from the Table Editor which are no longer used as they were affected by
the change in files.
Deprecated + deleted any unused code too

## Summary by CodeRabbit
* **New Features**
* Enhanced the policy editor with a centralized set of reusable
templates, including general table templates plus predefined Realtime
and queue access templates.
* Updated the table creation flow so it no longer auto-generates
additional RLS policy drafts.
* **Bug Fixes**
* Improved the policy table header badge layout for clearer RLS/API/lock
indicators.
* Simplified policy preview/save behavior so only meaningful edits are
reflected in the applied SQL.
* Streamlined the table-creation success messaging to remove conditional
failure details.
* **Tests**
* Updated/removal of policy and table-creation test coverage to match
the new behavior.

## 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
