Switch to internal search API

[nohr-ai]

Currently, the wrapper uses semi-public API endpoints to get information from Masterblaster, but this information is often not very detailed. I.e. information about linked game accounts is completely hidden behind an internal ID.

We can use the internal search API which returns more information about linked accounts.

There is no alternative until MB adds information about linked accounts in their public endpoints.

This will require a complete revamp of the objects

• Can create generics here to improve dev time until the APIs are stable
