BFD-4764: Prior Auth Server Implementation

[mel1-G]

JIRA Ticket:
BFD-4764

What Does This PR Do?

• Separates prior auth into two tables: idr.prior_auth and idr.prior_auth_item
• Implements the prior authorization mappings on the server
• Supports filtering by _source=CWF. Prior Auth eobs will always be returned by default otherwise.

MISC:

• cleans up ClaimAuditStatusCode since we stopped relying on it to determine the outcome on an EOB in 4593: BFD-4593 Add EOB Outcome Search #3174
• Implements the missing mappings for ClaimAuditStatusCode and ClaimPaidStatusCode
• Adds support to collect metrics on our executor
• renames the samhsa_filter metric to transform so our dashboard uses the correct metric

Notes:

• The data quality of prior auth is...not great. We still have some open questions and future meetings with IDR. This is why prior auth is behind a feature flag for prod. We'll only be serving synthetic data for now.
• Searching for prior auth's by id currently is not supported. This is why I short circuit relying on our SourceFilterParam. I left it out since it turns out to have a large blast radius. It can be done but as a future effort.
