Install libmsquic system-wide in the QUIC dev image so .NET can find it

Browse source 
Finding 8(c): the dev image builds the Node bridge's own libmsquic copy into
a build-local directory (scripts/build-quic-native.sh), which is never on the
loader's search path. .NET's System.Net.Quic resolves "libmsquic" through
that path independently and failed with PlatformNotSupportedException before
this. The smallest honest fix: dpkg -i the same pinned 2.5.9 deb (same URL,
same SHA-256 as the build script) system-wide and run ldconfig, so both the
Node bridge's own copy and .NET's independent resolution find a libmsquic.

Changes the image; the new tag is cultlib-quic-native-dev:75cb89e73850
(first 12 hex of this file's sha256), built fresh on Yggdrasil.
