revert(site): restore classic Habbo landing with soft theme polish

Replace the premium dark-gaming redesign of home, login and register with
the original classic landing (Habbo sky background, AuthTopBar, SurfaceCard
layout). Keeps the theme background visible again and adds a subtle
theme-aware brand halo behind the hero/Frank plus a soft primary glow on
card hover.

Also upgrades dependencies: next 16.3.5, vite 8.3.0 (typescript 7.0.2 was
already latest). Temporarily lowers pnpm minimumReleaseAge to 60 min so the
fresh 16.3.5 release can be installed; restore to 1440 once it is 24h old.
