fix(audit): correct + unify entity_type label map to match server values

Audit Log + dashboard feed used legacy keys (invoices_invoice, offers_quotation, trips, vehicles) that never matched the server's entity_type (invoice, quotation, trip, vehicle, ...) and omitted all warehouse_* entities, so many audit rows showed raw English. Single source of truth in lib/entityTypeLabels.ts, keyed to the actual EntityType values, with Czech labels for every type the server writes.
