Replace console frontend with unified findings pages

Add FindingsPage, FindingDetailsPage, and CreateFindingDialog
supporting all finding kinds (nonconformity, observation, exception)
with filtering, sorting, and audit linking.

Remove the separate nonconformity and continual improvement pages,
routes, and graph hooks. Update sidebar navigation, routes, and
components for nullable audit framework field.
