tui: bug fixes

[oliver-sanders]

tui: add offline commands

• Add support for the play and clean commands.

zmq client: raise WorkflowStoped not ClientTimeout

• WorkflowClient could raise ClientTimeout for stopped workflows.
• Closes TUI disconnects from workflow and has to be restarted #4654

tui: disable mutations for stopped workflows

• Closes TUI crashes with traceback when pressing Enter on stopped workflow #4647

tui: fix context menu for cycle points

• Closes tui: context menu for cycle points has the context of workflow #4629.
• Also adds the node ID to the context menu.

Note: This PR includes a sneaky enhancement (offline) which shouldn't really be going into a
RC release.
It's small enough and Tui as an experimental interface is supplementary enough I think its ok, but happy to cherry-pick and delay to 8.0.1.

Requirements check-list

• I have read CONTRIBUTING.md and added my name as a Code Contributor.
• Contains logically grouped changes (else tidy your branch by rebase).
• Does not contain off-topic changes (use other PRs for other changes).
• Applied any dependency changes to both setup.cfg and conda-environment.yml.
• Tui has no test framework for live testing at the moment
• Appropriate change log entry included.
• No documentation update required.

Poking tests

[MetRonnie]

Tested out manually, fixes the reported bugs.

Only thing is there is a delay of a couple of seconds between hitting enter on one of the offline commands in the menu and the menu closing

[oliver-sanders]

That's the time it takes for the command to run (blocking).

✅ Can confirm that this definitely fixes #4654 , #4647 and #4629.

I'm concerned about the bug shown below, although it might want spinning into a new bug report:

output.mp4

Essentially - stop returns control to you before the mutation finishes, and you can bring back the menu and ask for stop a second time after the workflow has stopped, and this causes a crash with traceback. Mentioned here rather than a separate issue because traceback refers to Exception raised by code in this PR.

@oliver-sanders your choice whether you want to fix or log this bug. I'm otherwise happy enough that this answers its original purpose that it can go in.
