refactor: rename frontend/ to web-player/ and format with prettier

Updates the compose build context, the Dockerfile header, the package
name and the docs. The compose service and container keep the name
frontend/musify-frontend, since nginx routes to http://frontend:3000.

The source files also carry the first prettier pass, so the rename and
the reformat land together for them.

 - **Svelte 5 runes siempre:** `$props()` con `interface Props`, `$state`, `$derived`, `$effect`. Nada de `export let` ni `$:`. `{#each}` siempre con clave.
 - **Server-only bajo `$lib/server/`**; nunca importado desde cliente.
 - Datos SSR vía `load` en `+page.server.ts`/`+layout.server.ts` → prop `data`.
