separate Multi Coins and Monero into distinct account types with startup login choice

- Removed monero from shared networks array; monero is now its own separate account type
- Added accountType state (null/'multi'/'monero') to wallet, stored in memory only
- Added login(type) method: chooses between EVM vault flow and Monero RPC flow
- Added logout() method that resets all per-account state
- On app startup, user picks Multi Coins (ETH/BSC/Polygon) or Monero
- isLocked getter now checks accountType === 'multi' instead of excluding monero by network id
- Moved ETH/BSC/Polygon routes under /multicoin/ base path
- /multicoin, /multicoin/bsc, /multicoin/polygon with updated navTarget routing
- Root / shows welcome/login choice, redirects if already logged in
- Fixed moneroListWallets timing: runs inside login('monero') after RPC manager exists
- Removed cross-tab links between monero and multicoin, only logout remains
