feat: redesign wallet login and favorites, fix desktop/mobile bugs

- Remove forced BNB chain switch on injected login (signature is chain-agnostic)
- Refine isMobileDevice so touch Macs stay on desktop flow
- Wire RainbowKit/WalletConnect as a real MetaMask/imToken QR fallback,
  gated on a valid VITE_WALLETCONNECT_PROJECT_ID
- Rebuild login modal: single desktop primary action, collapsible other
  methods, mobile open-app fallback feedback, brand icons
- Add My Favorites entry points (header, mobile menu, wallet dropdown)
- Favorites page: error retry, mobile filter drawer
- Auto sign-out and re-login prompt on favorites 401
- Full native translations for all wallet strings across 7 locales
