✨ Add --interactive Mode

[fredrik0x]

🕓 Changelog

This PR adds a feature to calculate hashes offline using an --interactive mode. When using --interactive mode, a user will be prompted to provide values for various parameters such as version, to, value, and others. If the user leaves any parameter empty, the default value displayed in the terminal will be used. These defaults are either retrieved from the Safe transaction service API or, in case of failure, fall back to zero values. This allows a user to customise the parameters or proceed with the API-sourced defaults.

IMPORTANT:

• Leaving a parameter empty will use the value retrieved from the Safe transaction service API, displayed as the "default value". If the value is unavailable (e.g. if the API endpoint is down), it will default to zero.
• If multiple transactions share the same nonce, the first transaction in the array will be selected to provide the default values.
• No warnings will be shown if multiple transactions share the same nonce. It's recommended to first run a validation without interactive mode enabled!
• Some parameters (e.g., version, to, operation) enforce valid options, but not all inputs are strictly validated. Please double-check your entries before proceeding.

Example:

./safe_hashes.sh --network arbitrum --address 0x111CEEee040739fD91D29C34C33E6B3E112F2177 --nonce 234 --interactive

Interactive mode is enabled. You will be prompted to enter values for parameters such as `version`, `to`, `value`, and others.

If it's not already obvious: This is YOLO mode – BE VERY CAREFUL!

IMPORTANT:
- Leaving a parameter empty will use the value retrieved from the Safe transaction service API, displayed as the "default value".
  If the value is unavailable (e.g. if the API endpoint is down), it will default to zero.
- If multiple transactions share the same nonce, the first transaction in the array will be selected to provide the default values.
- No warnings will be shown if multiple transactions share the same nonce. It's recommended to first run a validation without interactive mode enabled!

WARNING: The transaction includes an untrusted delegate call to address 0x111CEEee040739fD91D29C34C33E6B3E112F2177!
This may lead to unexpected behaviour or vulnerabilities. Please review it carefully before you sign!

WARNING: This transaction uses a custom gas token and a custom refund receiver.
This combination can be used to hide a rerouting of funds through gas refunds.
Furthermore, the gas price is non-zero, which increases the potential for hidden value transfers.
