Refactor parameter typing

[calebbourg]

Description

This PR refactors how we type incoming parameters for certain types of requests.

It adds a QueryFilterMap for type safety around parameters used to filter database queries.
It adds a related IntoQueryFilterMap trait which provides the mechanism for translating types between application layers.

This way we can provide types for endpoint parameters in the web layer and then translate that data into types understood and used by domain and entity_api without these lower layers needing to depend on web (avoiding circular dependency)

This a step toward my current goal of removing web dependency on anything other than domain

Changes

• Adds QueryFilterMap
• Adds IntoQueryFilterMap
• Updates web::error::Error

Testing Strategy

I tested this via Rapidoc and against the FE

Next

• Apply this pattern to other endpoints
• Re-Export any necessary entity_api or entity types through domain
• Remove web dependencies on entity_api and entity
• Add data validation mechanism to domain
• Allow for partial updates to data (for user, coaching session, etc. updates)

Just one minor thing to adjust, this looks fantastic. Nice evolution of our new domain layer on top of entity_api and encapsulating types that really don't need to be exposed.

This is nice, I didn't know how to use ref like this in such a way as to examine it for pattern matching without consuming/moving it.

I didn't know about it either!
