Fix log tags + SAVE_LANG bridge bug

panel_base: add _MODE_LOG_TAG map + _tag() function so Panel
registered/opened use [LAYERS], [TOOLBAR] etc. instead of [EBENEN]/[OBERLEISTE]

toolbar: _open_dossier_settings_panel now uses a custom _SettingsBridge
that actually handles SAVE_LANG -> writes lang to settings + reloads
all panels. Previously the default _SatelliteBridge only handled SAVE/CANCEL
so language switching did nothing.
