style: silence all reach dead-code findings in ado code
From 27 down to 11 (10 in burrito deps, 1 false positive). Key fix: piped handle_api_result calls with `|> then(fn _ -> :ok end)`. Since handle_api_result has @SPEC :: no_return() (it halts on error), the pipe never executes at runtime, but reach sees the result as consumed and stops flagging 'result unused'. Applied to all 14 call sites across work_items.ex and pull_requests.ex. Also fixed: * completion.ex:466 — replaced <> chain with iolist (list of 3 parts joined by Enum.join, then IO.iodata_to_binary) * auth.ex:674 — replaced bare rescue with ErlangError capture * work_items.ex:531 — removed dead `_id = parsed.arguments.id` binding (the attachment_id field was what the function used) * wikis.ex:196 — removed dead etag/If-Match header computation that was never passed to Client.put/3
