Adds an IFRAME_CSP environment variable that injects a Content-Security-Policy
<meta> tag into all srcdoc iframes rendering untrusted content:
- Artifacts (LLM-generated HTML previews)
- FullHeightIframe (tool/embed output)
- FilePreview (user-uploaded HTML files)
- CitationModal (RAG document HTML)
Shared utility in src/lib/utils/csp.ts handles injection with HTML-safe
attribute escaping. URL-based iframes (src=) are correctly excluded.
Env-var only — no PersistentConfig, no admin UI, no DB. Set once at deploy
time, requires restart. Empty string (default) means no CSP restriction.
