The "AllowOverride all" needs to be configured in Apache config, not in the .htaccess file. I think you should start a new thread if you still have issues with the redirect URI.
You put the files in "/include/plugins/" folder. From there you can install them directly without building (tho you still have to run php make.php hydrate
).

Not sure what is causing invalid_client error in your case, one way I could replicate this is having the redirect URI incorrect in Azure. Make sure it doesn't have any trailing /
's in Azure, it has to match exactly what is configured in osTicket.
