EZP-23986: As an editor, I want to have a navigation hub to navigate through the PlatformUI

[dpobel]

JIRA: https://jira.ez.no/browse/EZP-23986

Description

Completing the navigation hub implementation (follow up of #162).

Main changes:

• names of the zone
• admin is a zone with a specific style
• the navigation menu disappears if no zone is selected (like on the dashboard)
• the navigation appears if the selected zone has more than one item (Platform zone or Admin zone in the screencast)
• if the zone has exactly one navigation item, choosing the zone is like clicking on the item (Studio zone in the screencast)

Screencast:

Tasks:

• Rename the Create, Deliver, Optimize zones to Platform, Studio and Studio Plus
• Remove the hint on each zone
• Hide/Remove eZ Exchange for now
• Change Administration to be a new zone
• Add the navigation items (dashboard, section, system info) for the administration
• Add the custom styles for the Administration zone
• Hide the navigation no zone is selected (for instance on the dashboard)
• Display the navigation only when needed
• Improve the transition when the navigation menu appears/disappears (out of inspiration for now)
• When choosing a zone, load the route associated with the first navigation item ?

self note: missing ATTRS level!

Think we can remove the ., not part of the screenshoot I have seen so far and as PM said that was not needed. To stay consistent with this word use other placed, otherwise you can probably also expand it to Administrator like the other places in the UI, up to you.

+0,9

[dpobel]

@andrerom any reason to have downgraded your "+1" to a "+0.9" (which does not help)

[andrerom]

Just that I'm not so familiar with this part, so if I put a +1 it is not really a indication I have properly reviewed it. But I see your point that it can be misunderstood as meaning I'm saying we could do better or similar.

+1 FWIW
