feat: WalletConnect - advanced error handling

[dianasavvatina]

Proposed changes

Significantly improved error handling:

• on user reject, now send the response to the dApp
• handle TezosOperationError: pass data about failure to dApp. Now tests on failure pass in Taquito Test dApp
• provide unique and understandable error text to user (allows to google for the same problem)
  • if the error text is parsed, it's provided. If not, the error is more generic. Details are provided since they are unique for the
    contract involved by the user.

The implementation follows:

• https://specs.walletconnect.com/2.0/specs/clients/sign/rpc-methods
• https://www.jsonrpc.org/specification section 5.1 Error object

Types of changes

• Bugfix
• New feature
• Refactor
• Breaking change
• UI fix

Steps to reproduce

1. connect via WalletConnect Taquito Test dApp https://taquito-test-dapp.pages.dev/
2. run tests. All should pass:

  "Contract call with int",
  "Contract call with (pair nat string)",
  "Contract call that fails",
  "Contract call that fails with int",
  "Contract call that fails with (pair int string)",

3. run test "Contract call with int" and close the request on wallet side. Make sure that dApp received code and message.
4. run TezosProvider dapp, feat: added tezos-provider dapp example reown-com/web-examples#697
5. Connect to ghostnet
6. Run Sign and close the request on wallet side. Check that dApp received code and message about user reject
7. Run Send transaction and close the request on wallet side. Check that dApp received code and message about user reject
8. Run delegate twice for the same address. Make sure that dApp received code, message and data
