Fixes a critical heap buffer overflow in nginx's map directive regex handling (CVSS 9.2). The vulnerable range is 0.9.6 through 1.31.2; this bumps the 5.0 branch's nginx package to the patched 1.30.4 stable release. The six CVE backport patches (CVE-2025-53859, CVE-2026-27654, CVE-2026-32647, CVE-2026-27651, CVE-2026-27784, CVE-2026-1642) previously applied on top of 1.26.3 are dropped, as all six fixes are included upstream in 1.30.4.

Summary
Bumps nginx from 1.26.3 to 1.30.4 on the 5.0 branch to fix
CVE-2026-42533, a critical heap buffer overflow (CVSS 9.2) in nginx's
map directive regex handling.
Changes
CVE-2026-32647, CVE-2026-27651, CVE-2026-27784, CVE-2026-1642) that
were applied on top of 1.26.3 — all six are included upstream in
1.30.4, so re-applying them would either be redundant or fail to
apply against the updated source.

Testing
Not build-tested locally (RPM toolchain build not set up on my
machine); relying on CI for build validation.
