## 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.

## 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`.
