## 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

**Stack 1/6** of the TanStack Start migration (#46424), split into
reviewable, independently-mergeable PRs.
> [!IMPORTANT]
> **Next stays the default and only active framework after this PR.**
This wires up the Vite/TanStack-Start build pipeline behind the
`STUDIO_FRAMEWORK` flag, but there are no TanStack routes yet — so the
TanStack build isn't functional or tested until later PRs in the stack.
Nothing about the Next build, dev, or deploy changes behaviourally here.
## What's in this PR
- **Dispatch:** `dev`/`build`/`start` now go through
`scripts/dispatch.js`, which runs the Next variant unless
`STUDIO_FRAMEWORK=tanstack`. The original commands are preserved as
`dev:next`/`build:next`/`start:next`.
- **Build pipeline:** `vite.config.ts`, `serve.js`, `smoke-server.mjs`,
vite/tanstack deps, `turbo.jsonc`.
- **`tsconfig.json`:** `jsx: react-jsx`, `moduleResolution: Bundler`,
`target: ES2022`. Because `include` is `**/*.ts(x)`, this re-typechecks
the whole app, so the companion adaptations below land with it.
- **Shared adaptations (companions to the tsconfig change):**
`BufferSource` casts, `packages/ui` unused-`React` import removals, etc.
- **Routing/middleware plumbing:** `next.config.ts` +
`redirects.shared.ts` (redirect rules now shared with `vercel.ts`),
`proxy.ts`/`start.ts` middleware + `hosted-api-allowlist.ts`.
## Verification
Run locally off `master`: frozen install ✓, `studio` typecheck ✓, **Next
build ✓** (compiles + generates all routes), lint ratchet ✓ ("some rules
improved"), prettier ✓.

## Summary by CodeRabbit
* **New Features**
* Added a hosted API endpoint allowlist to return 404 for non-supported
`/api/*` routes.
* Introduced a TanStack route-migration checklist and expanded TanStack
Start routing support.
* **Improvements**
* Enhanced deployment refresh/detection by tightening cookie handling
for “latest deployment” updates.
* Centralized redirect/maintenance-mode rules for consistent platform vs
self-hosted behavior.
* Improved production serving with a dedicated static + proxy server and
a post-build smoke test.
* **Dependencies**
* Updated TanStack-related packages and React Table/query tooling
versions.
* **Documentation / Chores**
* Updated formatting and tooling config; added shared build environment
parsing utilities.
