Add dark mode support with appearance picker and fix hardcoded colors

Add user-facing appearance setting (System/Light/Dark) wired via
preferredColorScheme at the app root. Replace hardcoded .black tints
and foreground styles with .primary so toolbar buttons and text remain
visible in dark mode. Remove profile picture from settings and
SwiftSoup from acknowledgements.
