Add Settings | General | Environment Variable Settings Tab

[Omzig]

Summary of the new feature / enhancement

As an ops person, I want to know what environment variables have been picked up by the system so that i can quickly troubleshoot my psu instance.

Benefits

• enables playwright integration testing
• improves transparency in the framework
• reduce confusion
• improve container support

Proposed technical implementation details (optional)

Environment Variable Settings Tab Example

Name	Value	Description	Possible Values
PSU_DISABLE_WIN_AUTH	true	does stuff to iis for windows authentication	true, false
PSULICENSE	****	Contents of the PSU License File	???????
PSU_APP_PAGE_MAX	[not set label?]	Sets the Max Pages allowed in the browser session before it deletes the session	1-1000

i guess there is room to extend this idea, maybe the setting in here has a Source like the license table.

• Environment Variable
• Main appsettings.json
• appdata appsettings.json override
