Mirror synced plugins across case variants, fix OMOD logging

syncPluginsBack previously updated the profile from the newest case
variant but left the stale sibling (e.g. lowercase plugins.txt after
LOOT edited Plugins.txt) untouched in the prefix, so anything reading
the prefix before the next deployPlugins saw divergent content. Mirror
the newest variant into every sibling after the profile sync.

installer_omod.py called mobase.log / mobase.LogLevel which the Python
bindings do not expose, crashing .omod installs with AttributeError.
Route messages through stderr so the Python runner forwards them to
MOBase::log::error.
