ec574f3a51 fix(studio): pass Authorization header to assistant list_policies tool (#50756)
<!-- ccr-slack-attribution -->

thread](https://supabase.slack.com/archives/C051L8U2EJF/p1789995309253479?thread_ts=1789995309.253479&cid=C051L8U2EJF)_

Resolves AI-1246

## Problem

**Before:** The Assistant's `list_policies` tool fails in about 70% of
traces. It only "succeeds" when the org has AI opt-in disabled, because
then it returns the privacy stub and never makes a request. When opt-in
is enabled, it runs the pg-meta query server-side with no
`Authorization` header, so the request is unauthenticated and fails. The
Assistant then falls back to `execute_sql`.

**After:** `list_policies` sends the caller's `Authorization` header,
the same way `execute_sql` in `studio-tools.ts` already does, so it
returns the project's RLS policies.

## Solution

`getTools` already receives `authorization` but didn't pass it to
`getSchemaTools`. This PR passes it through. `list_policies` builds `{
Authorization }` from it, and `getDatabasePolicies` gets an optional
`headersInit` argument that it forwards to `executeSql`, the same
pattern `getDatabaseFunctions` uses. Existing client-side callers of
`getDatabasePolicies` don't change.

Files: `lib/ai/tools/index.ts`, `lib/ai/tools/schema-tools.ts`,
`data/database-policies/database-policies-query.ts`, plus tests in
`lib/ai/tools/schema-tools.test.ts` (new) and
`lib/ai/tools/index.test.ts`.

## Review instructions

1. Read `schema-tools.ts` and compare it with the `authHeaders` handling
in `studio-tools.ts` (`execute_sql`).
2. On the preview, use an org with AI opt-in set to at least "schema"
and ask the Assistant to list the RLS policies on `public`.
`list_policies` should return the policies without falling back to
`execute_sql`.

Local gates (all passed):
- `pnpm typecheck` in `apps/studio` (next typegen + `tsc --noEmit`)
- `npx eslint` on touched files: 0 errors. The 2 warnings are on lines
this PR doesn't change.
- `npx vitest run lib/ai/tools/schema-tools.test.ts
lib/ai/tools/index.test.ts lib/ai/tool-filter.test.ts`: 24/24 passed. I
also ran the new header test against the old `schema-tools.ts` and it
failed, as expected.
- `SORT_IMPORTS=false npx prettier --config prettier.config.mjs --check`
on touched files

Follow-up, not in this PR: `getRlsKnowledge` in `fallback-tools.ts`
(self-hosted path) also calls `getDatabasePolicies` without headers,
even though a `headers` object is already in scope there.
