fix: ticketing identity lookup after BSON round trip + WeKan live test

- live testing against a real WeKan v9.36 found that the driver decodes
  nested extra.ticketingIdentities as bson.D, so identity lookups silently
  returned empty and consultants were skipped; handle bson.D/bson.M/map
- integration regression test pinning the BSON round trip
- opt-in live test (go test -tags=wekanlive) verifying TestConnection,
  FetchUpdated (assignee + member fallback), key listing, since-filter and
  unknown-identity rejection against a real instance
