- Queue No (Opd.php::autoCreateOpdQueue, Opd_prescription.php::opd_prescription_save
and ::ensurePrescriptionSession): changed MAX(queue_no) query to JOIN through
opd_master.doc_id instead of trusting opd_prescription.doc_id, ensuring queue
numbering is strictly per-doctor per-day regardless of stale doc_id values in
opd_prescription rows.
- OPD appointment list: replaced auto-reload-on-digest-change with a manual
'Refresh' button. When the 8s digest poll detects new data the button turns
yellow with a 'New' badge; the page only reloads when the user explicitly clicks
it, preventing disruptive mid-session reloads."
