Danny White f7454cf94e feat(studio): oauth impersonation warning on authorize (#48162) 
## What kind of change does this PR introduce?

Feature + docs. Stacked on #48161 (logo contract /
[DEPR-604](https://linear.app/supabase/issue/DEPR-604/define-connect-logo-asset-and-variant-contract)).

## What is the current behavior?

After #48161, curated logos only resolve from allowlisted `redirect_uri`
hosts. A requester can still present a trusted partner **name** (e.g.
Claude) while redirecting to an unrelated remote host; the UI shows
Supabase alone but does not call out the mismatch.

## What is the new behavior?

- Shows a caution admonition when the requester name looks like a
trusted partner (Claude, Cursor, ChatGPT/OpenAI, Perplexity) but
`redirect_uri` is a **remote** host outside that partner's allowlist.
- Skips localhost / loopback redirects for the caution (common for local
MCP clients); those still get curated logos when the name matches a
trusted partner.
- Highlights the footer redirect URL in warning colour when the caution
is shown.
- Documents the behaviour in the Connect interstitials pattern.

### To test

Real MCP clients (Claude, Cursor, etc.) only send users to
**production** `/authorize`, so you cannot drive a local or preview
Studio build from those tools. Use a Network override instead:

1. Start Studio and sign in (`pnpm dev:studio`, or use the [Vercel
preview](https://studio-staging-git-danny-oauth-impersonation-warning-supabase.vercel.app/)).
2. Open `/dashboard/authorize?auth_id=foo` (any `auth_id` is fine; the
real response may 404) ([Vercel
preview](https://studio-staging-git-danny-oauth-impersonation-warning-supabase.vercel.app/dashboard/authorize?auth_id=foo)).
3. DevTools → **Network** → find `GET
…/platform/oauth/authorizations/foo` (or whatever id you used).
4. Right-click → **Override content** (enable Local Overrides / pick a
folder if prompted).
5. Paste one of the payloads below (status **200**), save, then reload
the authorize page.
6. Keep `expires_at` in the future so the request does not look expired.

#### Impersonation caution (trusted name + remote non-allowlisted
redirect)

Expect:

- Supabase alone (no curated Claude mark)
- Caution: “Redirect does not match this app name”
- Footer redirect URL in warning colour

```json
{
  "name": "Claude",
  "website": "https://claude.ai",
  "icon": null,
  "domain": "claude.ai",
  "redirect_uri": "https://evil.com/callback",
  "expires_at": "2099-01-01T00:00:00.000Z",
  "scopes": ["organizations:read", "projects:read"],
  "approved_at": null,
  "registration_type": "dynamic"
}
```

src="https://github.com/user-attachments/assets/e6eee016-5710-41ba-9925-87511e009e22"
/> |

#### Localhost MCP: no caution

Expect curated Claude + Supabase pair (name match + loopback), **no**
caution, normal footer colour. Local MCP clients often use loopback
redirects.

```json
{
  "name": "Claude",
  "website": "https://claude.ai",
  "icon": null,
  "domain": "claude.ai",
  "redirect_uri": "http://127.0.0.1:42813/callback",
  "expires_at": "2099-01-01T00:00:00.000Z",
  "scopes": ["organizations:read", "projects:read"],
  "approved_at": null,
  "registration_type": "dynamic"
}
```

src="https://github.com/user-attachments/assets/79f36865-3c8e-43e5-9490-24288efc74aa"
/> |

#### Legitimate curated partner: no caution

Expect curated Cursor + Supabase pair, no admonition, normal footer
colour.

```json
{
  "name": "Cursor",
  "website": "https://cursor.com",
  "icon": null,
  "domain": "cursor.com",
  "redirect_uri": "https://cursor.com/callback",
  "expires_at": "2099-01-01T00:00:00.000Z",
  "scopes": ["organizations:read", "projects:read"],
  "approved_at": null,
  "registration_type": "dynamic"
}
```

/> |

#### Unrelated name + remote redirect: no caution

Expect Supabase alone (no icon), no admonition.

```json
{
  "name": "Acme Tools",
  "website": "https://evil.com",
  "icon": null,
  "domain": "evil.com",
  "redirect_uri": "https://evil.com/callback",
  "expires_at": "2099-01-01T00:00:00.000Z",
  "scopes": ["organizations:read", "projects:read"],
  "approved_at": null,
  "registration_type": "dynamic"
}
```

Danny WhiteandJoshen Lim e19cd1863d feat(studio): connect logo contract for authorize (#48161) 
## What kind of change does this PR introduce?

Feature + docs. Closes
[DEPR-604](https://linear.app/supabase/issue/DEPR-604/define-connect-logo-asset-and-variant-contract).

## What is the current behavior?

`/authorize` logo resolution trusted self-asserted requester `name` (and
similar) for curated MCP marks, fell back to a letter tile when there
was no usable icon, and always used theme-reactive tile chrome. This
includes the scenario when pairing against unclassified uploaded OAuth
app bitmaps.

## What is the new behavior?

- [Documents the Connect logo asset/variant
contract](https://design-system-git-danny-depr-604-connect-logo-contract-supabase.vercel.app/design-system/docs/ui-patterns/connect-interstitials#logos)
(default to light, keep pairs matched, no theme-recolour of vendor
SVGs).
- Resolves curated partner logos from allowlisted `redirect_uri` hosts
only (`claude.ai` / `anthropic.com`, `cursor.com` / `cursor.sh`,
`chatgpt.com` / `openai.com`, `perplexity.ai`).
- Unknown / missing / failed requester icons show `SupabaseLogo` alone
(no letter tile).
- Uploaded organisation OAuth app icons (unclassified bitmaps) pair with
fixed light tile chrome (`border-black/10 bg-white` / `SupabaseLogo
forceLight`) on both sides across Studio themes.
- Curated partners keep theme-reactive tiles and may use dark assets
when available.

### To test

Real MCP clients (Claude, Cursor, etc.) only send users to
**production** `/authorize`, so you cannot drive a local or preview
Studio build from those tools. Use a Network override instead:

1. Start Studio and sign in (`pnpm dev:studio`, or use the Vercel
preview once available).
2. Open `/dashboard/authorize?auth_id=foo` (any `auth_id` is fine — the
real response may 404).
3. DevTools → **Network** → find `GET
…/platform/oauth/authorizations/foo` (or whatever id you used).
4. Right-click → **Override content** (enable Local Overrides / pick a
folder if prompted).
5. Paste one of the payloads below (status **200**), save, then reload
the authorize page.
6. Keep `expires_at` in the future so the request does not look expired.

The fields that matter for this PR are `name`, `icon`, and
`redirect_uri`.

#### Curated pair (allowlisted redirect)

Expect Cursor mark + Supabase pair. Toggle light/dark: curated dark
assets may swap; tiles stay theme-reactive (`bg-surface-75`).

```json
{
  "name": "Cursor",
  "website": "https://cursor.com",
  "icon": null,
  "domain": "cursor.com",
  "redirect_uri": "https://cursor.com/callback",
  "expires_at": "2099-01-01T00:00:00.000Z",
  "scopes": ["organizations:read", "projects:read"],
  "approved_at": null,
  "registration_type": "dynamic"
}
```

#### Unknown → Supabase alone

Expect Supabase bolt alone. No letter tile. No curated mark even if
`name` says Claude.

```json
{
  "name": "Acme",
  "website": "https://acme.example",
  "icon": null,
  "domain": "acme.example",
  "redirect_uri": "https://acme.example/callback",
  "expires_at": "2099-01-01T00:00:00.000Z",
  "scopes": ["organizations:read", "projects:read"],
  "approved_at": null,
  "registration_type": "dynamic"
}
```

#### Spoofed trusted name, non-allowlisted redirect (logo only)

Expect Supabase alone (no Claude mark). This PR does **not** show the
impersonation caution (that is coming in #48162).

```json
{
  "name": "Claude",
  "website": "https://claude.ai",
  "icon": null,
  "domain": "claude.ai",
  "redirect_uri": "https://evil.com/callback",
  "expires_at": "2099-01-01T00:00:00.000Z",
  "scopes": ["organizations:read", "projects:read"],
  "approved_at": null,
  "registration_type": "dynamic"
}
```

#### Uploaded OAuth app icon → forced-light pair

Expect remote icon + Supabase pair with forced-light tiles
(`border-black/10 bg-white`) on both sides in light and dark Studio
themes. The icon URL below is the checked-in solid-colour Acme bitmap on
this branch.

```json
{
  "name": "Acme",
  "website": "https://acme.example",
  "icon": "https://raw.githubusercontent.com/supabase/supabase/danny/depr-604-connect-logo-contract/apps/design-system/public/img/icons/acme-oauth-icon.png",
  "domain": "acme.example",
  "redirect_uri": "https://acme.example/callback",
  "expires_at": "2099-01-01T00:00:00.000Z",
  "scopes": ["organizations:read", "projects:read"],
  "approved_at": null,
  "registration_type": "static"
}
```
