Resolves#4028 (client half — backend is openfrontio/infra#368, which
must be deployed first).
## Description:
Adds "Login with Google" to the client, alongside the existing Discord
login. Companion to the backend PR (openfrontio/infra#368).
- `Auth.ts` — `googleLogin()` (full-page redirect to
`/auth/login/google?redirect_uri=…`, mirrors `discordLogin()`).
- `ApiSchemas.ts` — `GoogleUserSchema` + optional `user.google` on
`UserMeResponseSchema`.
- `AccountModal.ts` — a "Login with Google" button (Google brand
guidelines: white surface, dark text, the multicolor "G" mark) in the
login options, and the logged-in view now renders a Google-authenticated
user's email (also added `google` to `isLinkedAccount()`).
- `en.json` — `main.login_google`.
- `resources/images/GoogleLogo.svg` — the Google "G" mark.
> **Draft.** Depends on infra#368 being deployed (the button hits the
live `/auth/login/google`).
## Please complete the following:
- [x] I have added screenshots for all UI updates <!-- TODO: add
screenshot of the Google button -->
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [x] I have added relevant tests to the test directory <!-- no client
tests exist for AccountModal/Auth; verified via tsc --noEmit + eslint.
Backend behaviour is covered in infra#368 -->
