fix(auth): move initialAuthState/AuthState to auth-types.ts

Server-action files ('use server') can only export async functions.
Exporting initialAuthState (object) caused:
  'A use server file can only export async functions, found object'
when sign-up form was submitted.

Moved AuthState type and initialAuthState const to lib/appwrite/auth-types.ts.
Updated 3 form components to import the const from the new location.
