Whmcs in Credit WHMCS Whatsapp notification module v20.30 v20.30

Hi. Because we are a comunity, ill share with you my cloned WHMCS whatsapp notification rewrited almost from scratch for my needs. Ive tested this module for 3 weeks now and seems that everything is working as it should
What i implemented in this module:

1. Consent of client (well, i think that client should decide if want, or not whatsapp notification)
   1. Client will decide if want or not to receive whatsapp notification, if its set to NO, he will not receive any whatsapp notification
   2. Client has option to chose what kind of notification want to receve
      • Ticket notification
      • Invoice notification
      • Other service related notification (suspension, activation, etc)
   3. In any case, the module will skip or not sending notification
2. Surpress invoices with zero (0) value
   • You can chose if you want to send to the client a zero invoice, in many contry (mine also) zero value invoice has no value so i have no reason to send this kind of invoice
   • If the checkbox is selected, all invoices with zero value will be surpressed (deleted) and client will be redirected to the service purchased with a fancy message under product (this message cand be setup under /hooks/ZeroInvoiceTweek.php).
   • If checkbox is not selected, the module will send normal notifications (invoice, product provisioning, details)
3. Daily report
   • Admin will receive a daily report (from the day before) (like daily cron email) but with a small report with:
     • New orders
     • Invoice unpaid
     • Overdue invoices
     • Suspended services
     • Income (today, this month, this year)

Whatsapp server is included in this archive. Also ive made some tweeks on instalation file (detect if php, mysq is installed, if not those will be installed). Also, on my test period, the server crashed multiple times, and not sending notification, thats because for some reason (couldnt see the code, its encrypted) the server creating a Zombie process instead of closing and open again. Ive managed to fix this with a simple bash script witch is searching if that zombie process exist, and if exist restart the whatsapp server (also included in file). so, fo whatsapp server you need to add 2 crons instead of one.
Tested with whatsapp bussiness, and its working, 3 weeks now with no downtime or disconectig from phone
