Allow To Be Over Quota Not Working Properly For Sub-accounts

Describe the bug
If a sub-account has used less than its allowed quota amount and bulk optimization is started, then things work as expected and it allows bulk optimization to continue in excess of the allowed quota amount. But if bulk optimization is stopped and the sub-account is already over the allowed quota amount, and you then try to start bulk optimizing again, you get the overquota alert and bulk optimization is not possible.

To Reproduce

1. Enter a sub-account's API Key in Imagify plugin settings page
2. Set the sub-account's quota amount to a low number and make sure it's used it all
3. Enable the "Allow to be over quota" setting for the sub-account
4. Try to start Bulk Optimization and you will get the "Out of quota" popup message

Expected behavior
Bulk optimization should be allowed to start when the "Allow to be over quota" setting is enabled, whether the sub-account is already over its allowed quota amount or not.

Additional context
In this scenario, optimization is still allowed to happen individually from within the Media Library (even when the sub-account is already over its limit).

Here is the case where this was happening for one of our users. I was also able to reproduce the issue on my test site.

• Reproduce the problem
• Identify the root cause
• Scope a solution
• Estimate the effort

Start by reproducing the issue from the Imagify plugin settings page with a sub-account already over quota, then compare the bulk optimization flow with optimization from the WordPress Media Library. Trace where the “Allow to be over quota” setting is checked and confirm that bulk optimization can start in both quota states when enabled.
