## Summary
Two surfaces were showing invalid Codex config keys that don't exist in
Codex's schema (which uses `additionalProperties: false`), causing
validation errors for users who followed the setup steps.
- **Studio Connect Sheet** (`connect.schema.ts`): removes the "Enable
remote MCP client support" step, which told users to add
`[mcp]\nremote_mcp_client_enabled = true` to `~/.codex/config.toml`.
Deletes the dead content component and updates tests.
- **Docs MCP panel** (`ui-patterns/McpUrlBuilder/constants.tsx`):
removes the `[features]\nrmcp_client = true` config block from the Codex
`alternateInstructions`. Keeps the valid authenticate (`codex mcp login
supabase`) and verify (`/mcp`) steps.
Closes
[AI-548](https://linear.app/supabase/issue/AI-548/bug-studio-mcp-connect-flow-shows-invalid-codex-config-guidance)
Fixes#43893
## Root cause
Both invalid keys were introduced in #42374 (Feb 2026). A full search
through the [`openai/codex`](https://github.com/openai/codex) git
history confirms neither `remote_mcp_client_enabled` nor `rmcp_client`
ever existed in any version of the codebase (neither the TypeScript CLI
nor the Rust rewrite).

This PR migrates the whole monorepo to use Tailwind v4:
- Removed `@tailwindcss/container-queries` plugin since it's included by
default in v4,
- Bump all instances of Tailwind to v4. Made minimal changes to the
shared config to remove non-supported features (`alpha` mentions),
- Migrate all apps to be compatible with v4 configs,
- Fix the `typography.css` import in 3 apps,
- Add missing rules which were included by default in v3,
- Run `pnpm dlx @tailwindcss/upgrade` on all apps, which renames a lot
of classes
- Rename all misnamed classes according to
https://tailwindcss.com/docs/upgrade-guide#renamed-utilities in all
apps.

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`.
## What kind of change does this PR introduce?
Chore
## What is the current behavior?
- We use the MCP client connect dialog in two places: Studio and Docs
- We duplicate image assets for each client in each of those two places
## What is the new behavior?
- Centralised assets
- Consolidation and simplification as a result of it all being a single
source-of-truth now
## To test
- [ ] Everything works as it did before across both Studio and
[Docs](https://supabase.com/docs/guides/getting-started/mcp)
- [ ] All MCP client images load as expected

This is the third and final PR to complete the new connect sheet.
First: https://github.com/supabase/supabase/pull/42367
Second: https://github.com/supabase/supabase/pull/42373
This re-adds the Direct, ORM, MCP tabs and their content, including via
connect.schema.
To test:
- Flag will be enabled on all staging projects
- Click connect and notice new Sheet
- Click all tabs and ensure content is correct
