….7.12 Ports the httpcore5-h2 and pgjdbc fixes from develop (fb_owasp_cves_20260709) onto the 26.3 release branch. Force org.apache.httpcomponents.core5:httpcore5-h2 to httpcore5Version (5.4.3) so the transitive 5.3.6 is upgraded past the vulnerable 5.4.2 ceiling, clearing CVE-2026-54399 (HTTP/1.1 parser DoS) and CVE-2026-54428 (HTTP/2 HPACK decoder DoS). Bump postgresqlDriverVersion 42.7.11 -> 42.7.12 for CVE-2026-54291, a channel-binding downgrade in pgjdbc 42.7.4-42.7.11 that silently drops SCRAM-SHA-256-PLUS MITM protection (fixed in 42.7.12). Suppress the CVE-2026-54428 false positive on the classic httpcore 4.x artifact, which has no HTTP/2 module and is not affected. Shaded copies of these libraries originate from labkey-api-jdbc and are addressed separately.

Rationale
Ports the OWASP dependency-check CVE remediations from develop (PR #1441, branch fb_owasp_cves_20260709) onto the 26.3 release branch. The 26.3 scan flagged CVE-2026-54399 / CVE-2026-54428 (httpcore5-h2 resolving transitively to 5.3.6) and additionally CVE-2026-54291 (postgresql JDBC driver pinned at 42.7.11 — a channel-binding downgrade fixed in 42.7.12; develop was already on 42.7.12).
