SEC-WEB-33: Replace raw diagram source and detailed error messages in
MermaidViewer error UI with a generic "Diagram rendering failed" message.
Detailed errors are logged to console.error for debugging only.
SEC-WEB-35: Add console.warn in useWorkspaceId when no workspace ID is
found in localStorage, making it easier to distinguish "no workspace
selected" from silent hook failure.

Add runtime type validation after all JSON.parse calls in the web app to
prevent runtime crashes from corrupted or tampered storage data. Creates a
shared safeJsonParse utility with type guard functions for each data shape
(Message[], ChatOverlayState, LayoutConfigRecord). All four affected
callsites now validate parsed data and fall back to safe defaults on
mismatch.
