feat: Implement user confirmation mode, request confirmation when running bash/python code in this mode

[adrgs]

What is the problem that this fixes or functionality that this introduces? Does it fix any open issues?
Implements #2308 enhancement

Give a brief summary of what the PR does, explaining any non-trivial design decisions

• Adds a new boolean setting called CONFIRMATION_MODE, which is false by default
• Adds a new toggle option in SettingsForm
• Implements 3 new states for the agents: AWAITING_USER_CONFIRMATION, ACTION_CONFIRMED, ACTION_REJECTED
• In confirmation mode, the bash/python actions will have confirm/reject buttons directly in the chat log
• Updated tests

Thanks a ton for this contribution!!
Backend part LGTM 👍 ! Can anyone from the front side take a look?

plus: right now, confirmation mode has to be set at the beginning of the conv, and there's no way to switch them on and off during an interaction session. I guess the next step of improvement would be to support "switch them on/off on the fly" - let's open an issue to track this once this PR is merged :D

LGTM! @adrgs , could you please fix the lint and the failed unit tests?

[amanape]

Also, don't forget to lint your code in order to merge changes!

[adrgs]

Thanks everyone for the great feedback! I've added a new commit with the changes.

Let me know if there is anything else to be done. Thank you

I think CmdKillAction no longer exists, merge issue?

[amanape]

Hey! Sorry for the delay. It seems your package-lock.json and package.json are not in sync. Try removing the package-lock.json and running npm install again.

[adrgs]

Added, sorry for that.

[amanape]

It looks that one of the Python tests are failing. I'm not sure if it is due to flakiness or due to the changes you have introduced.

@enyst Could you confirm if it is due to the change they made to agent.py?

[yufansong]

I guess it should be flakiness. Rerun the test to see the result.

[adrgs]

Added missing is_confirmed in test outputs

Thanks a lot for this cool feature! Awesome stuff
