fix(launcher): restore open_in_os win routing, fix cfg_json in IDB, fix display state

open_in_os = 'win': get_launch_profile() now maps pptx→pptxwin, ppt→pptwin,
odp→odpwin, pdf→pdfwin when open_in_os is 'win', routing to the Windows-variant
launch profiles (Parallels/CrossOver). Was never wired in native mode — feature
was silently lost in the MasterKey→Launcher port.

cfg_json missing from properties_to_save: the per-file display override was
always read as undefined from Dexie because cfg_json was never saved. Added
cfg_json to properties_to_save so display_override and any other cfg fields
persist correctly. NOTE: IDB_CONTENT_VERSIONS for event_file is not yet wired;
existing devices need a manual cache clear to pick up the new field.

Display override button: removed $ae_loc.is_native gate — must be configurable
from any device ahead of the event, not only on the podium Mac.

Display toggle persistence: quick_display_mode now reads from and writes to
$events_loc.launcher.display_mode so the last-set state survives page reloads
instead of always defaulting to 'extend'.
