Automatically close billing periods when a project is marked inactive

Description:
When a job wraps up and is marked inactive, its billing periods stay open, so each one has to be closed by hand on every finished project. It would save a step if marking a project inactive also closed any billing periods still open on it.

This would also keep inactive jobs fully wrapped up across the app, alongside the Hide Inactive Projects filter in Accounts Payable By Vendor.
