fix: GET /hub/dashboard now honors from/to date range

Previously always scoped parcels_received_today, batches_sent_today,
exceptions, and parcels_sorted to "since midnight today", ignoring any
from/to query params — so any non-default range silently returned
zeros. Now parses optional from/to (YYYY-MM-DD, same semantics as
GET /hub/report) and defaults to today when omitted.
