Add About / Support page (roadmap #4)

- New 'about' view wired into sidebar nav (♥ support) and App.tsx
- Sections: in-app zap button (reuses ZapModal + NWC infra), Lightning
  address QR + copy, Bitcoin address QR + copy, Ko-fi link, GitHub link,
  version/tech credits footer
- QR codes rendered as SVG via react-qr-code (no canvas dependency)
- lightning: URI and bitcoin: URI formats for wallet-scannable QR codes
- Tasteful and non-nagging — lives in the nav, never pops up unprompted
