Add support/sales/controlling dashboards with KPIs, trend charts and
risk indicators. Add debitor communication timeline, contact filters,
system recommendations engine, and configurable controlling risk rules.
Rename search→index to fix query-string preservation on back navigation.
Remove fake escalation rate metric, add KPI info tooltips, and switch
trend chart colors to red (created) / green (closed) for clarity.
