Improve loading indicator.

• Remove indicator's background, add shadow.
• Found there's existing loading state, use it to show/hide indicator, remove newly add isLoading. There's also existing LoadingOverlay page, but tried that looks not well with current UI, so keep using new loading indicator.
• Add effecting state. We don't want see indicator when playing VFX, but still can't allow user change traits when playing VFX, so have to add effecting state.
