Support XDC-prefixed recipient addresses

[Copilot]

XDC wallets commonly expose EVM addresses with an xdc prefix. These recipients were rejected by send validation and could leave transaction actions disabled.

• XDC address handling

  • Add chain-aware validation for xdc-prefixed addresses on XDC only.
  • Normalize valid XDC addresses to canonical 0x format before calldata, gas estimation, and broadcast.

• Send UI

  • Apply XDC-aware validation when entering a recipient and enabling transaction review.

• Coverage

  • Add unit tests for valid normalization, invalid XDC input, and rejection on non-XDC chains.

  XDC_CHAIN_ID,
)
// => "0xEC2136843a983885AebF2feB3931F73A8eBEe50c"

• Fixes Support xdc-prefixed addresses as valid format #41
