Add update_config write path (TWS 10.44 / server 221) (#708)

* Add update_config write path (TWS 10.44 / server 221)

Fluent Client::update_config() (sync + async) returning an
UpdateConfigBuilder to push partial config edits back to the gateway.

- Builder: .api()/.orders()/.lock_and_exit()/.message()/.accept_warning()/
  .reset_api_order_sequence() -> .submit(); generic over client, per-feature
  submit() in sync_impl/async_impl (rule 12).
- Reuses the read-path domain types as write input (Option fields + Default).
- Domain->proto encoders mirror the proto->domain decoders; new
  UpdateConfigResponse + ConfigWarning domain types.
- Features::UPDATE_CONFIG gate (server 221); UpdateConfigResponse registered
  in text_request_id_field so it routes by request_id.
- One-shot request/response (no library re-submit loop); caller echoes
  warnings via .accept_warning() to proceed, mirroring C# EClient.updateConfig.
- Field-minimal testdata builder; 100% coverage on the new code.

Live smoke test deferred: the write path mutates gateway settings.

* Add bulk .messages()/.accept_warnings() setters to update-config builder

Closes the Vec-vs-singular composability gap so a caller can round-trip
Config.messages / UpdateConfigResponse.warnings in one call (precedent:
MarketDataBuilder generic_ticks + add_generic_tick).

* Make update-config submit tests symmetric

Bring the async request-body test to full parity with the sync mirror
(adds lock_and_exit + per-element assertions); trim the sync
response-decode test to the wiring-critical fields since exhaustive
proto->domain mapping is owned by the decoder unit test.
