Implements a new job that automatically approves recharge invoices
meeting certain criteria (type, status, paid date).

The job checks for invoices of type "Recharge" with "PendingApproval"
status that have been paid for a specified number of days.  If these
conditions are met, the job automatically approves the invoice and the
associated debit recharge accounts.

Adds necessary configuration settings and database context setup.

Adds tasks to the pipeline to build and publish the auto-approve job.
Also adds .NET 8 SDK usage to the pipeline build steps.

Automatically approves recharge invoices when the customer email matches the user email and the invoice has debit recharge accounts.
This speeds up the approval process for self-recharge scenarios.

financial approvers. This allows tracking of when and to whom
approval requests were sent. Updates the invoice service to
return the approval model.
