www/angie: Security update to 1.12.2

This maintenance release fixes CVE-2026-90439:

When using an OpenSSL version without native HTTP/3 support (3.5.0
or earlier), if the default server for the address that accepted a
regular HTTPS request also used HTTP/3 (the listen directive with the
quic parameter, possibly on a different port), while a server block
without HTTP/3 was selected by domain name (SNI), limited worker process
memory corruption or a worker process crash could occur
(CVE-2026-90439); the fix was ported from nginx 1.31.6.
