Fix permission UI layout jumping and center footer text

- Added fixed height and padding to "Granted" labels to match button sizes
- Prevents layout jumping when transitioning between button and granted state
- Small buttons use height 22px, large buttons use height 38px
- Centered the footer text in DashboardSettingsView permissions section
- Consistent visual appearance across all permission UI elements
