fix: Make all tests pass!

Delete TokenTransfer.sol
Make slither happy

Bugfixes:
- Executors
  - Ekubo:
    - Fix the POOL_DATA_OFFSET value and remove sender from callback data
    - Use SafeERC20
  - Maverick and Univ2: Use safeTransfer and not safeTransferFrom
  - Univ3: update expected data length
  - Univ4: update the selectors (the signature changed)
- Router:
  - For split swap we don't need to pass the tokenInReceiver, it should always be the router address
  - For single and sequential: change order of the parameters (to be before the permit2 specific objects)
- Encoders:
  - Update selector signatures
  - For split swap pass the transfer_from (we might not need to if the token in is ETH)
