fix: drop URL::forceRootUrl (Livewire/CSRF break on tenant subdomains)

forceRootUrl forces ALL generated URLs to APP_URL (service.mir.md).
On psauto.service.mir.md, Livewire-generated POST URLs targeted
service.mir.md instead of psauto, so CSRF/session cookies didn't
match → silent auth failure.

Keep forceScheme('https') so Cloudflare → Traefik → Octane proxy
chain doesn't generate http:// links, but let Laravel use the
actual request host for everything else.

Also: TextInput->lowercase() removed (not in Filament v5);
slug uses dehydrateStateUsing(strtolower) + visual CSS lowercase.
