fix: Remove account_id from params since it is not used (#13116)

account_id was permitted in strong parameters, allowing authenticated
admins to transfer resources (Portals, Automation Rules, Macros) to
arbitrary accounts.

 Fix: Removed account_id from permitted params in 4 controllers:
  - portals_controller.rb
  - automation_rules_controller.rb
  - macros_controller.rb
  - twilio_channels_controller.rb
