[IMP] *: Do not pollute message and notification box when installing an industry

[amas-odoo]

• Remove res_users.xml forcing notification_type='inbox' so modules generate
  mails again.
• Read generated mails via _read_group and browse related records.
• Inspect linked mail.activity and handle upsell activities separately:
  • Identify upsell activities from note content.
  • Ignore upsell activities without external IDs when their count matches
    generated mails.
  • Process remaining activities to detect missing contexts.
• Suggest required contexts to prevent message/mail pollution.
• Log warnings with external IDs and recommended contexts.
• Add validation on XML nodes to ensure required mail-prevention
  contexts are set.
• Introduce helper log_warning to standardize missing-context warnings.
• Add specific checks:
  • slide.channel: ensure publish_template_id is set to False.
  • sale.order.action_confirm: require mail_auto_subscribe_no_notify and
    mail_notrack when subscription SO is present.
  • Functions defined in FUNCTION_CONTEXT_DICT_WITHOUT_USER:
    enforce mail_auto_subscribe_no_notify.
  • write calls updating user_id / user_ids: require
    mail_auto_subscribe_no_notify to prevent unwanted followers/mails.
• Safely parse function context using literal_eval with fallback handling.

Context Used

• mail_auto_subscribe_no_notify: Prevents notifications that are normally sent
  when users are automatically added as followers. By default this is False,
  meaning notifications are sent — enable it to stay silent.
• mail_activity_quick_update: When creating activities for other users, this
  avoids sending them a notification about the new activity.
• mail_notrack: During create or write, disables field change tracking so no
  automatic “value changed” messages are posted.
• no_mail_to_attendees: Stops email notifications from being sent to event attendees.
