#5 from checkpoint feedback: /workers/<id>/ now has an Absences tab
showing YTD totals (chip row) + 50 most-recent absences (table).
Admin dashboard adds a conditional 'X absent in last 7 days' alert
card (only renders when count > 0; links to filtered /absences/).
CLAUDE.md gets a new Absence model entry + URL routes + dedicated
'Absence-to-PayrollAdjustment cascade' section. Reason-badge CSS
moved to static/css/custom.css as single source of truth. 4 new tests.
