The /api/employees/:id/score endpoint previously only returned data from
the active_cpas_scores view (active_points + violation_count for the 90-day
window). The EmployeeModal score cards reference total_violations and
negated_count which were undefined, causing blank displays.
Now queries the violations table directly for all-time totals alongside
the rolling 90-day active data.
- POST /api/violations now accepts acknowledged_by and acknowledged_date
- Both fields added to AMENDABLE_FIELDS whitelist for post-submission edits
- Acknowledgment data persisted to DB and passed through to PDF generation
