python3-aiohttp: fix CVE-2026-54273

This patch applies the reviewed upstream fix shown in [1]. The
advisory identifying the fix is referenced in [4].

The follow-up from [2] is kept as a separate recipe patch. It adapts
the declined WebSocket-upgrade replay from [3], applies the queue
pause after replay, and includes the corresponding regression tests.

The generated aiohttp/_http_parser.c changes are omitted. The
recipe-time Cython regeneration introduced with CVE-2025-69224
regenerates that file from the patched _http_parser.pyx before the
accelerated parser is compiled.
