Auth WEB - Update the GET and PUT calls for configurations

[JazzarKarim]

As of right now, the GET call for configurations is grabbing all the configuration items although the UI doesn't use most of them.

As for the PUT call, we're putting the entire configurations array although only one thing has changed and that's the value of the dissolution batch size. We need to only change that.

Need to handle:

• Use new GET endpoint with query param to grab only what is needed (the endpoint is going to be worked on in Legal API - Add filter to configurations endpoint #21442)
• PUT only the part that is needed
• Add/update unit tests if necessary

Tested in Dev and able to query with specific param for retrieving that configuration.

GET :

https://legal-api-dev.apps.silver.devops.gov.bc.ca/api/v2/admin/configurations?names=NUM_DISSOLUTIONS_ALLOWED

Now we can just send a configuration that needs to be updated in the array instead of sending all the configurations list.
PUT:

Verified the GET and PUT operations in Test env and working as expected.
