fix: dark mode event colors, sidebar height, calendar default, photo badge

- event-config: all bgClass/borderClass get dark:bg-*-950/50 + dark:border-*-800 variants — fixes bright pastel backgrounds in dark mode
- nav: h-screen → h-[100dvh] — fixes sidebar bottom buttons hidden behind mobile browser chrome
- calendar: selectedDay defaults to today, never null — events shown immediately on load
- timeline + dashboard: photo indicator (ImageIcon) on events with metadata.photo
