Mubashir WhatsApp for WHMCS - v1.5.0
====================================

INSTALL / UPGRADE (from 1.4.0)
1. Backup the old folder, then upload the "wa_mubashir" folder to:  <whmcs>/modules/addons/   (overwrite).
2. Open Addons > Mubashir WhatsApp once. Tables/columns are created/upgraded automatically.
3. Templates tab: click "Reset to English Defaults" if you still see Roman Urdu / old messages.
4. Setup > Addon Modules > enable new toggles:
   - Invoice Due Reminders (3d / 1d)
   - Service Renewal Reminders (7d / 3d)
5. Cron (every 5-15 min) — same as before, now also processes scheduled messages + reminders:
   */10 * * * * php -q <whmcs>/modules/addons/wa_mubashir/cron.php >/dev/null 2>&1

WHAT'S NEW IN 1.5.0
- Professional easy-English templates for all events (invoice, ticket, service, domain, order, quote, admin alerts)
- Many more variables per event (invoice_link, days_until_due, product, suspendreason, ticket_link, etc.)
- Improved Client Summary "Send WhatsApp" box (cleaner layout, schedule option)
- Ticket View page: same Send WhatsApp box
- Auto Reminders via cron: invoice due 3 days & 1 day before; service renewal 7 & 3 days before (deduplicated)
- Scheduled Messages: schedule a message for a later time from the client box
- Opt-out / blacklist: opted-out clients are skipped for auto + scheduled sends
- New tables: mod_wa_mubashir_optout, mod_wa_mubashir_scheduled, mod_wa_mubashir_reminders
- Reset to English Defaults button on Templates tab

Still recommended / future:
- Full Reports charts tab, multi-language template sets, API health dashboard (structure ready)

SECURITY
Rotate any old exposed API tokens. Keep api_token only in module Settings.
