meta.ini: lowercase code keys to match normalize, kill dup writes

normalizeMetaIniCase folds keys to lowercase, but readMeta/saveMeta and
the install paths still used CamelCase ("installationFile", "gameName",
"nexusDescription", etc.). Qt6 IniFormat is case-sensitive on Linux, so
setValue under CamelCase wrote a NEW key alongside the lowercase entry
left by normalize, and value() reads with CamelCase missed the lowercase
key and fell back to defaults — saveMeta then persisted those defaults
under CamelCase. Net effect: every save grew meta.ini by ~12 duplicate
lines (e.g. installationFile=  +  installationfile=<real value>;
gameName=SkyrimSE  +  gamename=Skyrim).

Lowercased all per-mod meta.ini key names in modinforegular.cpp,
installationmanager.cpp, and organizercore.cpp. Section/group names
(installedFiles, Plugins, INI Tweaks) stay CamelCase because normalize
preserves section headers verbatim.
