fix: serve datastar locally and clean up session/route config

Replace CDN-hosted datastar beta.11 with local v1.0.0-RC.7 to fix
client-side expression incompatibilities with the Go SDK. Also fix
quoted CSS class keys in data-class expressions, harden session cookie
settings (named cookie, Secure flag), simplify SetupRoutes to not
return an error, and regenerate templ output.
