feat: audit enhancement

[paymonsattar]

Describe your changes

Enhances the case history audit trail to capture granular, field-level change details across all case entities.

• audit entries now record old and new values, file names, folder names, and entity context instead of generic "X was updated" messages. Templates use metadata placeholders resolved at display time.
• New resolver layer — added dedicated resolvers for diffing complex entity types (contacts, inspectors, procedures, outcomes, related/linked cases) that compare old and new state by ID and produce specific audit entries for each added, updated, or deleted item and sub-field.
• Moved audit recording to the right lifecycle point — file upload auditing moved from individual upload to commit time so only finalised files are audited. File move auditing moved from the selection view to the save controller. Both now distinguish single vs bulk actions.
• Previous state capture — updateCaseData now fetches the full case (with relations) before updating so resolvers can compare old vs new values. Entra group members are loaded for user display name resolution.
