Replaces the disabled CSP middleware with a working implementation: - Generates a per-request nonce for script-src - Injects nonce into the inline SvelteKit bootstrap script - Uses 'strict-dynamic' so dynamically imported modules are trusted - SPA fallback serves index.html with CSP header

Closes #164
Enables the previously disabled CSP middleware. The old implementation was disabled because SvelteKit's inline bootstrap script would be blocked by a strict policy.
