[STC-836] Fixes for the Copy numeric ID feature

[thykel]

Ticket

https://community.openproject.org/projects/STC/work_packages/STC-836/activity

What are you trying to accomplish?

Address following bugs:

• In semantic mode, newly created wps trigger 404 when we click on that menu item.
• In numeric mode, on the WP listing page, this menu item is visible (triggering the same error) but shouldn't be visible at all.
• We want a different icon for the numeric ID menu item

Screenshots

What approach did you choose and why?

• Add a copy handler to fix the 404
• Add a missing actions filtering mechanism to WpContextMenuActions
  • Also, make the pre-existing WpSingleContextMenu mechanism switch to this one, as it's cleaner than setting hidden
• Change the icon to the recommended one

Merge checklist

• Added/updated tests
• Added/updated documentation in Lookbook (patterns, previews, etc)
• Tested major browsers (Chrome, Firefox, Edge, ...)

@thykel I suggest squashing the last two "fix tests" commits
