## Context
This is just a pre-requisite to consolidating the project creation UI as
there's another page that has the project creation flow too
[here](https://github.com/supabase/supabase/blob/master/apps/studio/pages/integrations/vercel/%5Bslug%5D/deploy-button/new-project.tsx).
So the next step will just be to use the same `ProjectCreationForm`
there
No functional changes here - just moving things around
## To test
- [ ] Verify that project creation still works

## Summary by CodeRabbit
* **New Features**
* Added a full “create project” experience with eligibility-aware
defaults, advanced configuration sections, optional GitHub integration,
and compute-cost confirmation when applicable.
* **Improvements**
* Enhanced project-creation success/error handling and navigation.
* Refined CLI backup/restore dialogs (better layout/wording,
accessibility updates, and improved section separation).
* **Documentation**
* Standardized all relevant documentation links across the app using a
shared `DOCS_URL` source.
* **Refactor**
* Refactored the “New Project” page to delegate the wizard UI and flow
to a reusable creation component.

## Summary
- pg_graphql 1.6+ disables schema introspection by default, which breaks
GraphiQL's docs explorer and field autocomplete. This PR adds an in-app
notice + confirmation flow so users can opt into (or later opt out of)
introspection without leaving the GraphQL tab.
- Introspection state is read from, and written to, the `@graphql(...)`
directive embedded in the target schema's Postgres comment (`public` by
default). Other directive options the user has set are preserved when
the introspection key is toggled.
- Ships `parseSchemaComment` / `buildSchemaCommentWith` helpers (with
unit tests) and a `useSetIntrospection` mutation hook, plus collapsible
disabled-state and dismissible enabled-state notices rendered above
GraphiQL. GraphiQL is re-mounted after a toggle so it re-runs
introspection.
## Test plan
- [ ] On a project with pg_graphql >= 1.6 and introspection disabled:
disabled-state notice appears, confirm modal shows the SQL that will
run, enabling re-mounts GraphiQL and populates the docs explorer.
- [ ] On a project with introspection enabled: small enabled-state
banner appears, disabling clears the docs explorer and updates the
schema comment.
- [ ] Existing `@graphql({...})` options (e.g. `inflect_names`,
`max_rows`) survive a toggle; malformed directive text is replaced and a
warning is shown in the confirm modal.
- [ ] On pg_graphql < 1.6 (or extension not installed): no notice
renders, GraphiQL behaves as before.
- [ ] Collapsed-disabled-notice state persists per project via local
storage.
