- Inject Security service into all 3 audit subscribers to resolve
actor profile from authenticated user (fixes "Par Inconnu" issue)
- Add CustomFieldValue tracking: insertions, updates, and deletions
on custom field values now produce audit log entries on the parent
entity (composant, piece, product) with field name prefix
"customField:{name}"
