Danny White 1131e3e2ce fix(ui): default Button variant to default instead of primary (#50160)
## What kind of change does this PR introduce?

Bug fix / design-system alignment for the legacy `Button` from `ui`.

## What is the current behavior?

Omitting `variant` on the legacy `Button` falls back to brand-green
`primary`. That makes accidental greens easy, and it is hard to spot the
real main action on busy pages.

## What is the new behavior?

- Legacy `Button` now defaults to neutral `default`
- Intentional primary CTAs (create, save, submit, marketing CTAs, and
matching `ButtonTooltip` usages) now set `variant="primary"` so their
appearance is unchanged
- Neutral actions that previously relied on the old fallback (cancel,
close, back, dashboard nav, and similar) become grey/white
- Design-system docs updated; regression tests cover the new default

`Button_Shadcn_` is unchanged. It already uses its own CVA default.

This is PR 1 of 2 in a stack. PR 2 drops now-redundant
`variant="default"` props.

## To test

Studio (http://localhost:8082):

- `/sign-in`: Sign in stays green
- Open a project → Database → Tables: New table stays green
- Auth → Users → Invite: Invite user stays green; Cancel / dismiss
controls stay neutral
- Project Settings → General: edit a field so Cancel and Save appear.
Cancel is neutral, Save is green

Design system (http://localhost:3003):

- Components → Button: default demo is neutral; primary demo is green;
featured preview is the default variant

Marketing (optional):

- www header: Start your project stays green; logged-in Dashboard is
neutral

## Summary by CodeRabbit

- **Style**
- Buttons now default to a neutral style, while primary actions across
Studio, documentation, marketing pages, forms, dialogs, and error states
use prominent primary styling.
- Updated button examples and previews clarify the distinction between
default and primary variants.
  - Event registration now includes a directional arrow icon.

- **Tests**
- Added coverage confirming default button styling and explicit primary
styling behave as expected.
- Updated related test fixtures to use primary styling where
appropriate.

Supabase UI Patterns

This package should be used for components which are built using NPM libraries (react-markdown, reactflow for example), which make no sense to be included in all apps. It should also be used for components which are constructed using various components from the ui package.

This package does not have a barrel file - each component has to be imported from its index (ui-patterns/PrivacySettings, for example). This is intentional so that adding a new component which is used only in 1 or 2 apps doesn't burden the rest of the apps.
