feat(settings): tray store gains mac_hide_dock + close-to-tray opt-out

Add a mac_hide_dock column (with migration) to the shared tray settings
store for the upcoming macOS close-to-tray Dock-icon toggle, and flip the
close_to_tray default to true (opt-out: closing sends the window to the
tray and keeps the app running).
