Switch the settings layout content wrapper from overflow-hidden to overflow-visible in SettingsLayoutView, UserSettingsLayoutView and AdminSettingsView so multiselect dropdowns and tooltips can render outside the panel without being clipped.
Adds AdminFontView with package list, install buttons, status indicators and toast notifications backed by /api/v1/fonts/status and /api/v1/fonts/{package}/install. Wires the new admin.settings.fonts lazy route and a Languages-icon menu entry under Admin → Settings.
