Ivan Vasilov 69ce915a9e chore: Rename SUPABASE_PUBLISHABLE_OR_ANON_KEY to SUPABASE_PUBLISHABLE_KEY for all blocks (#42652)
This PR renames all `SUPABASE_PUBLISHABLE_OR_ANON_KEY` env vars into
`SUPABASE_PUBLISHABLE_KEY` to make the new API keys default. This is in
coordination with the rest of the docs.

I've also cleaned up the `blocks/vue` package from unused files.

## Summary by CodeRabbit

* **Breaking Changes**
* Public environment variable names renamed from PUBLISHABLE_OR_ANON_KEY
→ PUBLISHABLE_KEY across all framework integrations; update your
environment configs.

* **Documentation**
* All framework guides, .env examples and registry docs updated to use
the new variable names.

* **Chores**
* Cleaned up UI registry/templates: some example Vue registry items and
autogenerated registry artifacts were removed or simplified.

## Installation
<BlockItem name="supabase-client-nextjs" description="Supabase Client for Next.js" />
## Folder structure
<RegistryBlock itemName="supabase-client-nextjs" />
## Usage
This block installs a Supabase client for connecting your Next.js project to Supabase. It's designed for use with the App Router and fully supports server-side rendering (SSR).
If you've already set up your Supabase client—either using the `npx create-next-app -e with-supabase` template or another method—you can continue using your existing setup.
### Getting started
After installing the block, you'll have the following environment variables in your `.env.local` file:
```env
NEXT_PUBLIC_SUPABASE_URL=
NEXT_PUBLIC_SUPABASE_PUBLISHABLE_KEY=
```
- If you're using supabase.com, you can find these values in the [Connect modal](https://supabase.com/dashboard/project/_?showConnect=true&connectTab=frameworks&framework=nextjs) under App Frameworks or in your project's [API settings](https://supabase.com/dashboard/project/_/settings/api).
- If you're using a local instance of Supabase, you can find these values by running `supabase start` or `supabase status` (if you already have it running).
<Callout type="warning" className="mt-4">
{' '}
This Supabase client is built for SSR with the Next.js App Router. If you're building a React SPA,
use the [React SPA client](/ui/docs/react-router/client) instead.{' '}
