Update database-services.ts getCustomQueries

[robertandremitchell]

Description:

Once work is complete to add query_data and conditions_list to the query table in the database, we will need to refactor this section of code: https://github.com/CDCgov/dibbs-query-connector/blob/main/query-connector/src/app/database-service.ts#L622

We should be able to avoid as many joins and just pull data from query. This may require updating the interface to not pull from valuesets or to reflect the JSON we create for query_data.

This should allow us to also in the case of superadmins get rid of any WHEREs. which only exist now to speed up processing. The limiting factor should be done based on user permissions, which we may need to add here or could potentially be accomplished in an alternative method.

Acceptance Criteria:

• Fetches valuesets / concepts for conditions pulls from the query_data column
• My Queries table pulls from the query table rather than hardcoded
• Constants that tie the demo query options to labels / values / etc aren't so duplicative
