Adds scripts/pkg-cache-repos.sh and wires it into Dockerfile,
Dockerfile.fpm, Dockerfile.shared-httpd and Dockerfile.shared-ols. With
--build-arg PKG_CACHE=http://192.168.1.40 (CT130 pkg-cache), dnf/apt go
through the LAN cache. That cache fetches from the Remi/EPEL/AlmaLinux/
Ubuntu/LiteSpeed origins over HTTPS, with fallback tiers and
stale-on-error. Without the arg the script is a no-op and builds are
unchanged.
- rpm: each baseurl becomes "<cache>/<prefix>/... <origin>/...", so dnf
fails over to the origin if the cache dies mid-build
- every RUN restores the original repo files before it ends, so no
shipped layer carries the LAN address
- EPEL/Remi release RPMs come from the cache when it is set
- the php.net version gates are untouched
Dockerfile.litespeed/.lsphp are not wired yet (see docs/pkg-cache.md).
