Shopfloor feed resolves employee names live when none is stored

Photos already resolved through the directory at read time, but names
only came from the stored employeename column - empty after a
shopdb-only import, so recertification/recognition cards showed bare
SSOs. New resolve_employee_display_name in the employees plugin
(mode-aware: self-hosted table or external HR) backs a fallback in
both the single-card and split-per-employee paths; stored names still
win when present.
