fix(push,cdr): honor Receiver.raw_token and add CdrLocation.evse_uid

Two OCPI compliance/interop fixes needed for CDR push to eMSPs that do
not base64-decode the auth token (e.g. DepotCharge):

- push_object now sends the raw auth token when Receiver.raw_token=True,
  instead of always base64-encoding for 2.2.x/2.3.x. Some eMSPs compare
  the literal Token header value, so a base64-encoded token is rejected
  with 401 "Unknown token".
- CdrLocation (2.2.1 and 2.3.0) now includes the spec-required evse_uid
  field. It was missing, so the lib silently dropped evse_uid from the
  serialized CDR, causing receivers to reject the push with 400.
