fix: total-timeout labeled 'timeout' in request_with_retries (dead branch live) (v0.1.5)

AW-1: request() wraps a total ClientTimeout's bare asyncio.TimeoutError before
request_with_retries sees it, so the dedicated 'timeout' branch was dead and its comment
lied. wrap it as aiohttp.ServerTimeoutError (which IS both a ClientError AND a
TimeoutError) so direct request() callers still get a typed failure (M1 preserved) while
request_with_retries catches the timeout case first and labels it 'timeout'.

verified by execution: request() raises ServerTimeoutError (typed, M1 intact);
request_with_retries returns reason='timeout'; control confirms a real client error still
labels 'client error'. sibling-grep: aioweb_tls/aiowebhooks catch ClientError/TimeoutError,
both of which ServerTimeoutError satisfies — no consumer break.
