ui: Miscellaneous Lock Session fixes

[johncowen]

Whilst reviewing #9930 and #10121 we noticed a few bugs that required fixing up within Lock Sessions in the UI.

The first and most important was that the Lock Session APIs changed shape back in 1.7 but the documentation doesn't reflect this change (https://www.consul.io/api-docs/session#sample-response-3) so I've already added an issue for this here #10095

The UI still expected the JSON response to be in the pre-1.7 shape so primarily this PR alters our mock API and the UI to the shape of the response as it is post-1.7.

Also:

Viewing a Session for a KV:

1. We noticed that the Name property is optional, so we only show this row if a Name is set for a session.
2. We noticed that this is the only place in the UI where we refer to a Node as an 'Agent' and is probably just a hangover from the original version of the UI, so we've changed this up here to use the word Node instead to match the rest of the UI.
3. There was a bug where we weren't showing the Delay or TTL here at all, so we fixed that here also.
4. We changed the order of the rows in the table to match the order of the information in our Lock Session listing page.

Lock Session Listing page/component:

1. We moved the CopyButton for the ID out of the dt and into the dd to make it visible/clickable.
2. Upgraded the tooltips to use a modifier style which we added in ui: Modifier based tooltips #9288
