Fixes DOCS-651
## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.
YES
## What kind of change does this PR introduce?
This adds a non-null assertion to a Supabase method that expects
non-null.
Additionally, it updates a label from 'Remix' to 'React Router'.
## What is the current behavior?
Two issues:
- Following the Auth client steps with React Router creates a
`deprecation` error and downstream Typescript errors.
- 'Remix' is renamed to 'React Router'.
> Remix and React Router are the same thing, made by the same people.
Remix was simply renamed React Router Framework Mode starting in version
7 of React Router.

/>
## What is the new behavior?
- Adding a non-null assertion clears up all error. Running the
application does not produce errors.
- Changing the label from "Remix" to "React Router" updates the dropdown
name to match the rebrand. Now, it does not look outdated and matches
the docs.

## Additional context
The task was to clarify our documentation on this page: [Create a
Client](https://supabase.com/docs/guides/auth/server-side/creating-a-client?queryGroups=framework&framework=react-router&queryGroups=environment&environment=react-router-loader#create-a-client)
However, the code sample in the docs is correct; the documentation in
**Dashboard** produced the errors.
## Future improvements
- To make this more robust, the code could have a single source of
truth.

## Summary
Removes `_DEFAULT` from the publishable key env var name across all
Connect and ConnectSheet framework content, so that e.g.
`NEXT_PUBLIC_SUPABASE_PUBLISHABLE_DEFAULT_KEY` becomes
`NEXT_PUBLIC_SUPABASE_PUBLISHABLE_KEY`. This matches the docs and sample
apps.
### Connect
- Next.js (App Router)
- Next.js (Pages Router)
- React (Create React App)
- React (Vite)
- Remix
- SolidJS
- SvelteKit
### ConnectSheet
- Next.js (App Router)
- Next.js (Pages Router)
- React (Create React App)
- React (Vite)
- Remix
- SolidJS
- SvelteKit
- Vue.js
- shadcn env step
Resolves FE-2934

## Summary by CodeRabbit
* **Bug Fixes**
* Standardized environment variable names in generated connection/setup
instructions: when a publishable key is present the templates now
reference the publishable env var (e.g.,
NEXT_PUBLIC_SUPABASE_PUBLISHABLE_KEY, VITE_SUPABASE_PUBLISHABLE_KEY,
REACT_APP_SUPABASE_PUBLISHABLE_KEY, etc.) with unchanged anon-key
fallback behavior.
* Updated cURL/tab placeholders to reflect the new publishable-key
identifier when hiding keys.

This PR moves several components which rely on `next` out of the `ui`
package to the `ui-patterns` package.
`ui-patterns` package is intented to be imported with specific imports
so it's ok if there are components reliant on `next` in there.
The `SonnerToaster` component has removed its dependency by requiring a
prop for `theme`.
This is part two of a [PR
breakdown](https://github.com/supabase/supabase/pull/42276) that
introduces our connect schema and how content is retrieved. This focuses
on the Framework tab to start.
Fields are generated and content is rendered using a connect.schema
file. This schema file defines modes, fields and steps. Each mode has a
set of fields. Each field can be dependent on another field. The steps
generated are then based off the values of the modes and fields. Each
step can also render varying content dynamically using a template
{{framework}}/{{frameworkVariant}}/{{library}} which just replaces those
values with what's in state (fields selected).
[Part one needs to be merged
first.](https://github.com/supabase/supabase/pull/42367)
The next stage will add back all other tabs and content.

This is the first smaller PR in the broader change of updating our
Connect dialog (see
[here](https://github.com/supabase/supabase/pull/42276)).
This PR focuses on decoupling the ConnectButton our of the Connect
dialog and into its own component . The button includes a flag to render
the new sheet. The new sheet is empty for the time being as the flag is
at 0%.
To test:
- Enable flag and click button, see new Sheet
- Disable and see old dialog
- Create a new project -> in getting started section see "connect to
app" step -> Click connect button and make sure it works

## Summary by CodeRabbit
* **New Features**
- Added a Connect button component and an alternative Connect sheet.
- Added curl syntax highlighting for code blocks.
* **Changes**
- Connection dialog moved to a controlled open-state pattern; Connect
replaced legacy entry points across the UI and can be feature-flagged.
- Connection actions simplified and no longer depend on framework
selection.
* **Removals**
- Removed legacy framework selector, default framework constant, and
related tests.
