ci(portal): sign orca webhook POST with HMAC-SHA256

When `orca webhooks add` registers a webhook it generates a signing
secret by default; orca then requires X-Hub-Signature-256 on inbound
POSTs (the public master at :6880 means anyone could otherwise fire
a deploy by crafting the JSON body).

Adds the signing step using the standard github-shaped header. The
secret is consumed from a new Gitea Actions secret ORCA_WEBHOOK_SECRET
on this repo — value provided out-of-band from the master.
