Drop per-venue request methods from `Client` 

Use dynamic lookups instead by mapping to the correct http session and
endpoints path using the venue routing/mode key. This let's us simplify
from 3 methods down to a single `Client._api()` which either can be
passed the `venue: str` explicitly by the caller (as is needed in the
`._cache_pairs()` case) or falls back to the client's current
`.mkt_mode: str` setting B)

Deatz:
- add couple more tables to suffice all authed-endpoint use cases:
  - `.venue2configkey: dict[str, str]` which maps the venue key to the
    `brokers.toml` subsection which should be used for auth creds and
    testnet config.
  - `.confkey2venuekeys: dict[str, list[str]]` which maps each config
    subsection key to the list of venue name keys for doing config to
    venues lookup.
- always build out testnet sessions for spot and futes venues (though if
  not set the sessions obviously won't ever be used).
- add and use new `config.ConfigurationError` custom exceptions when api
  creds are missing.
- rename `action: str` to `method: str` in `._api()` since it's the
  proper ReST term and switch what was "method" to be `endpoint: str`.
- mask out `.get_positions()` since we can get that from a user stream
  wss request (and are doing that).
- (in theory) import and use spot testnet url as necessary.
