Ap2 Sign Alias

Transition an alias contract to SIGNED.

Precondition: contract exists and is in PENDING (or already SIGNED, which is idempotent). The buyer_signature length is logged -- never the signature material itself.

SENTINEL_v1.0 (MP #55, Task 2.4): the Sentinel screens the signing request through the SemanticFirewall AFTER the contract / state preconditions and BEFORE the Advocate validation. Confirmed injection patterns return HTTP 403 sentinel_blocked; everything else falls through to the Advocate (Rule #7 fail-open).
