[dashboard] Misc outstanding issues

[svenefftinge]

Here're some more outstanding issues, feel free to resolve here or a new PR. (from @gtsiolis in #3496 )

• Avatar Menu actions don't work (settings / logout)
• When searching and focus is on the search text field, on ESC clear the search input.
• Pressing ESC opens up the "new workspace" (at least after it was opened once)
• Clicking Open in the more actions dropdown for stopped workspaces does not work.
• introduced aliases used in the wild (e.g. /settings, /upgrade-subscriptions)
• Persist top menu state on Workspaces and Settings
• Could we apply a subtle hover transition effect on everything? See also relevant discussion.
• When clicking on Workspaces the top menu always move to Active workspaces.
• Let's also change the font weight for more actions dropdown items to font-medium
  menu. Also, let's change the dropdown spacing from space-y-2 to space-y-1 and py-2 to py-1.
• What do you think of removing the responsive layout of the table? Is this easily turned off? If not, feel free to ignore for now.
• Can we also remove the responsive layout of the top menu and profile menu?
• Workspace more actions button should be visible only on hover. See similar approach in [dashboard] Re-implement running workspace selector for new dashboard #3464 (comment).

Adding the follow up issues from #3510 (review). /cc @jankeromnes @svenefftinge

• Let's truncate this as it can break the layout for this component! See [dashboard] Improve new workspace start experience ⚡ #3510 (comment)
• Can we center align all the elements within this div and also keep a fix width for the workspace reference? See [dashboard] Improve new workspace start experience ⚡ #3510 (comment).
• Both of these buttons lack hover state. Maybe we could add this on the button component in index.css. See [dashboard] Improve new workspace start experience ⚡ #3510 (comment).
