fix: notify ThemeSettingsRepository when cached profiles are loaded

loadCachedProfiles() sets activeProfileIndex but did not notify
ThemeSettingsRepository to re-read profile-scoped settings (theme,
amoled) from the correct profile key. This ensures theme and other
profile-scoped preferences are loaded from the correct profile
after the cached profile data is applied.
