- ForwardCompatIT: send a valid ExecutionChunk envelope with extra
unknown fields instead of a bare {futureField}. Was being parsed into
an empty/degenerate chunk and rejected with 400.
- ProtocolVersionIT.requestWithCorrectProtocolVersionPassesInterceptor:
same shape fix — minimal valid chunk so the controller's 400 is not
an ambiguous signal for interceptor-passthrough.
- BackpressureIT:
* TestPropertySource keys were "ingestion.*" but IngestionConfig is
bound under "cameleer.server.ingestion.*" — overrides were ignored
and the buffer stayed at its default 50_000, so the 503 overflow
branch was unreachable. Corrected the keys.
* MetricsFlushScheduler's @Scheduled uses a *different* key again
("ingestion.flush-interval-ms"), so we override that separately to
stop the default 1s flush from draining the buffer mid-test.
* executionIngestion_isSynchronous_returnsAccepted now uses the
chunked envelope format.
