feat(tangle-dapp): Add ERC-20 asset restaking

[yurixander]

Summary of changes

Provide a detailed description of proposed changes.

• ➕ Added support for restaking ERC-20 EVM assets. Note that only EVM accounts can restake ERC-20 assets.
• ➕ Deployed some dummy ERC-20 asset smart contracts to Tangle Testnet EVM in order to test & QA ERC-20 restaking flow. This helps skip the bridging step on testnet.
• ➕ ERC-20 asset balances are now shown on the Dashboard page.

What's left here:

• Deploy dummy ERC-20 smart contracts to testnet that give Alice or other testing accounts balances.
• Test ERC-20 restaking by restaking those ERC-20 assets that were deployed to testnet.
• Hard-code their addresses to be listed as assets when the active network is testnet.
• List ERC-20 vaults & balances on the Dashboard page.
