win32: preserve full version string in non-numeric build fields

meson.build's marketing version may carry a pre-release suffix like
"3.0.0~alpha1".  The build template previously joined the dotted parts
back into a string, dropping the suffix everywhere it landed:
PACKAGE_VERSION (About dialog, user-agent, tarball name) and the
StringFileInfo block (Windows file-properties dialog).

Split into two values inside version-template.ps1: $versionFull keeps
the full marketing string for those human-readable fields, while
$versionParts is the digits-only form for the numeric Win32 VERSIONINFO
FILEVERSION/PRODUCTVERSION quad that rejects non-numeric components.
poxchat.sln reorder is VS-autosave noise from opening the solution.
