fix(http): replace .expect() with match in webhook handler (#1133)

* fix(http): replace .expect() with match in webhook handler

Replace `.expect("checked is_none above")` with a proper `match` on
`webhook_secret.as_ref()`. The is_none-then-expect pattern was logically
safe but violates the project rule against .expect() in production code.

Update pre-existing test to expect SERVICE_UNAVAILABLE (503) instead of
UNAUTHORIZED (401) when the secret is cleared, since the None check now
returns early before signature verification.

* fix(ci): formatting + suppress no-panics false positive in test

- Collapse multi-line Some() to single line per rustfmt
- Add // safety: comment on test assert_eq to suppress CI grep
