- AxiamWebhooks
- Verifies the `X-Axiam-Signature` HMAC-SHA256 header AXIAM attaches to every webhook delivery (CONTRACT.md ยง13, T-145). Mirrors the server's signer (`crates/axiam-api-rest/src/webhook.rs`'s `compute_signature_v2`): the MAC covers the ASCII string `<t>.<raw_body>`, keyed with the webhook secret's raw UTF-8 bytes.
