Subject: [PATCH] fix(web): declare the three remaining implicit return types
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Residue from CodeRabbit's review of #1381 after ae2be83 and 5e69b7e landed
the substantive findings. Those two commits typed `upstreamFailure`,
`upstreamUnreachable`, and the `activateRequest` / `webhookRequest` /
`transcribeRequest` helpers; these three were missed:

- `getOpenAiHeaders` -> `Record<string, string> | null`
- `sdpRequest`       -> `Request`
- `upstreamResponse` -> `Response`

Types only — no behavior, no response shape, no test expectation changes.
`getOpenAiHeaders` already returned exactly this union on both paths, so the
annotation is descriptive rather than a narrowing.

Verified at this head: tsc clean, eslint clean, web suite 271 passed /
1 failed — the pre-existing billing-chat-gating timeout (#1116), matching
5e69b7e exactly.
