🚀 Feature: improve login page core web vitals

### 🔖 Feature description

Prerender the login page for improved core web vitals

### 🎤 Pitch

While investigating SvelteKit applications in the wild, I found that AppWrite consoles are written in SvelteKit and fail core web vitals. E.g. here's one such URL: https://auth.lucas-cm.com.br/login

A big contributor to this is that [SSR is disabled](https://github.com/appwrite/console/blob/92e7f4780738c16b0e403b69635b9d1d14041ce2/src/routes/%2Blayout.ts#L10), so just a blank page loads initially.

This could best be avoided by prerendering the login page.

(Alternately, the largest image on the page could be preloaded and you could render some image, background image, or text while the JavaScript is being fetched rather than leaving the page blank, but this would be more work, a worse user experience, and probably still worse on core web vitals)
