Scope Builder: `authFullChatClient` has wrong `aud`

[flo-bit]

Generated scope string when selecting authFullChatClient: include:chat.bsky.authFullChatClient?aud=did:web:api.bsky.app%23bsky_chat

Fails in social app fork, while this works: include:chat.bsky.authFullChatClient?aud=did:web:api.bsky.chat%23bsky_chat
