ZelisPaymentUpdateJob: Support .csv in addition to .zip for Payment Status Report files

### Describe the feature or problem you'd like to solve

The ZelisPaymentUpdateJob will only process file with a .zip extension. Zelis is having problems generating .zip files and asked if we can handle .csv instead.

### Proposed solution

Expand the file extension filter to accept both .zip and .csv by default.
As a suggestion, it may be worthwhile to consider either excluding the file extension completely so that it only considers the file name and extracting the file name filter content (currently "Payment_Status_Report") to a job parameter to make it easier to change this, going forward.

### Example prompts or workflows

_No response_

### Additional context

The ZelisPaymentUpdateJob job Parameters dictionary is already read from the master database Job record (see GetSftpArchiveDirectoryFromJobName as an example).

Start by locating ZelisPaymentUpdateJob and compare its file-name filtering with GetSftpArchiveDirectoryFromJobName, including how the Job Parameters dictionary is read. Confirm the expected Payment_Status_Report inputs and update the filter so both .zip and .csv files are processed, then run the job's existing tests or workflow to verify both extensions.
