www/nginx: security update from 1.26.2 to 1.26.3

<ChangeLog>

*) Security: insufficient check in virtual servers handling with TLSv1.3
   SNI allowed to reuse SSL sessions in a different virtual server, to
   bypass client SSL certificates verification (CVE-2025-23419).

*) Bugfix: in the ngx_http_mp4_module.
   Thanks to Nils Bars.

*) Workaround: "gzip filter failed to use preallocated memory" alerts
   appeared in logs when using zlib-ng.

*) Bugfix: nginx could not build libatomic library using the library
   sources if the --with-libatomic=DIR option was used.

*) Bugfix: nginx now ignores QUIC version negotiation packets from
   clients.

*) Bugfix: nginx could not be built on Solaris 10 and earlier with the
   ngx_http_v3_module.

*) Bugfixes in HTTP/3.
