CW-608-Fetch-And-Save-Icons-Of-ERC20-And-SPL-Tokens-When-Adding-Them (#1365)

* feat: Fetch and save icons of SPL tokens when adding them * feat: Implement fetch and save icons for ERC20 tokens when adding them * fix: Add moralisApiKey to evm secrets * Add check to ensure decimals cannot be zero * - Fallback to adding erc20 token from web3dart - Wrap fetching spl token icon in a try/catch block --------- Co-authored-by: OmarHatem <omarh.ismail1@gmail.com>
