Adjust nomenclature used in `IInputBox`

[guidanoli]

📚 Context

On #201, we've made some changes to address #2. Most importantly...

• Renamed input parameter as payload
• Renamed MAX_INPUT_SIZE constant as MAX_INPUT_PAYLOAD_SIZE
• Added PayloadTooLarge custom error

With #84, however, the Server Manager will not write just the payload to the rx buffer, but the whole input (payload and metadata) encoded as a Solidity function call.

✔️ Solution

We need to make the following adjustments to the IInputBox interface...

• Rename MAX_INPUT_PAYLOAD_SIZE constant as MAX_INPUT_SIZE
• Check if the whole input is smaller than the maximum size, not just the payload
• Rename PayloadTooLarge custom error as InputTooLarge (and its arguments as well)

No problem. What is the overlap, though?

The "blockchain agnostic input" issue involves correctly naming input and payload, which covers this issue.
