Adds an opt-in inbound HMAC scheme so a leaked URL alone is not enough
to forge deploy/sync requests — the caller must also know a separate
signing secret. Header format is X-Hub-Signature-256, matching the
Gitea/GitHub/GitLab convention so existing CI integrations work without
custom code.
Behaviour:
- per-project / per-site signing_secret is independent of the URL secret
- require_signature flag does a hard 401 on missing/invalid signatures
- even when require_signature is off, an *invalid* submitted signature
returns 401 — surfaces CI misconfiguration instead of silently passing
- comparison uses subtle/hmac.Equal (constant time)
Backend:
- store: webhook_signing_secret + webhook_require_signature columns on
projects + static_sites; scanProject helper, scan helpers updated; new
Set* helpers for both fields
- webhook/handler: verifyHMAC helper, body read once, integrated into
both project and site handlers
- api: per-entity signing-secret rotate / disable / require-toggle
endpoints under /api/{projects,sites}/{id}/webhook/...
Frontend:
- WebhookPanel gains optional signing handlers (no breaking change for
existing callers; signing UI hides when handlers aren't wired)
- one-shot reveal of the issued secret with copy + dismiss
- ToggleSwitch for require-signature, disabled until a secret is issued
- en/ru i18n strings
Tests:
- HMACRequiredAndValid (200 + deploy fires)
- HMACRequiredButMissing (401, no deploy)
- HMACPresentButWrong (401 even when require_signature=false)
- HMACOptionalUnsignedAccepted (200 when neither configured)
