Edit/Delete with Checkpoints

[liwilliam2021]

We now make a checkpoint after every user message so when a user edits a user message. Now when a user has checkpoints enabled, upon deleting or editing a message they are asked if they would like to restore the checkpoint right before the message was sent

For future consideration: The state transitions during checkpoint restoration (task running → aborting → restoring → reinitialized → processing pending edits) could benefit from a formal state machine implementation to make the flow more explicit.

LGTM.

There's a lot in this PR. Do you think we could break it down into smaller independent pieces, like for instance a PR to change when we do the checkpoint first? And then follow it up by using checkpoints for edit/delete?

@mrubens #6359 has been merged. I believe this pull request contains significant changes.

Currently, checkpoints can restore both tasks and files. However, checkpoint triggering is currently more file-dependent. Furthermore, checkpoints are currently guaranteed to be created before modifications are made. A more requested feature is #2943.

Hey @NaccOll We are aware of the changes to checkpoints done by this PR, we are working on a version of this PR that doesn't the checkpoint logic but achieves the same result

I will resolve conflicts based on this PR code, and adapting the new checkpoint generation timing (#6359), and finally complete the "Enhanced User Message Deletion Dialog" and "User Message Edit Functionality" mentioned in #7285. Although this is a content that has already been completed by this PR.
