Merge branch 'feature/inbound-api-full-response-audit': inbound API full request/response audit capture

Inbound API audit rows (Channel = ApiInbound) now capture request and
response bodies in full up to a configurable 1 MiB per-body ceiling
(AuditLog:InboundMaxBytes), instead of the global 8 KiB / 64 KiB caps
that other audit channels use. Implements the M5-deferred response-body
capture in AuditWriteMiddleware via a write-only Stream wrapper that
forwards every byte to the framework's response sink while bounding the
audit copy at the capture site (ArrayPool-backed for the request side).
Other channels untouched.

 - Script execution errors (500 responses) remain captured on the same `ApiInbound.Completed` row (response status + error fields) rather than emitting a separate failure-only event.
 - **Fail-soft semantics.** The audit write is synchronous (inline before the response is flushed), but failures are caught: a write that throws is logged and increments `CentralAuditWriteFailures` (see Health Monitoring #11) and the request still returns its normal HTTP response. A failed audit append never turns a successful API call into an error returned to the caller.
