fix(tree,jobs): Various fixes to improve tree UX; add checks for "Delete Job"

[traeok]

Proposed changes

This PR resolves the following issues:

• The "Delete Job" action showed an info message stating that the job was deleted, even in scenarios where an error occurred during deletion
• A check was missing for the optional paste APIs, which allowed the paste operation to run on unsupported nodes
  • Added an info message to inform users if the paste operation is unsupported
• Removed unneeded "node array" from pasteUss function, and fixed refresh after paste is complete (nodes now show up as expected)
• Removed check from the USS tree for newly-created nodes so that deleted nodes are removed from the tree
• "Directory nodes" (USS directories, PDS, and Jobs) and session nodes across all trees now update with their respective "collapsed icon" when collapsed.
• Add check for JCLLIB to appendSuffix function to format its members as JCL

Release Notes

Milestone: 2.11.1

Changelog:

• Fixed issue where USS nodes were not removed from tree during deletion. USS tree not updated with changes #2479
• Fixed issue where new USS nodes from a paste operation were not shown in tree until refreshed. USS tree not updated with changes #2479
• Fixed issue where the "Delete Job" action showed a successful deletion message, even if the API returned an error.
• USS directories, PDS nodes, job nodes and session nodes now update with their respective "collapsed icon" when collapsed.

Further comments

If possible, please try to break the USS tree when testing this PR 😅 I want to make sure that the nodes are staying up to date, and I'm not sure that I've exhausted all scenarios. Here's what I've tested so far:

• Delete a node in the root level of the USS session
• Delete a node in a sub-folder of the USS session
• Copy multiple files and paste into a folder within the USS session
• Copy multiple files and paste into USS session node

This seems exactly the same as the PR below:

• fix(job,uss): Remove extra 'delete job' msg; add check for paste APIs & fix refresh #2480

Also, thanks for adding JCLLIB to the appendSuffix method 😋

I'm running into a small issue in the dataset tree with the ID already being registered.
Steps:

1. Search for a dataset pattern, e.g. sys1.parmlib
2. Collapse the profile
3. Expand the profile
4. See this issue:

Everything else LGTM! 😋

@zFernand0 Yeah... 😅 I ran into some issues with the previous branch when trying to rebase off of maintenance, so figured a new branch/PR would be the quickest solution.

I haven't made any adjustments to the getChildren logic for the dataset tree yet, but I will look into fixing this as part of this PR 😁
