Admin console homepage - Registration status

As a system administrator, I can tell if my nuxeo instance is registered and until when

Context:
When an instance is not registered anymore, it will stop when it reaches specific thresholds (number of concurrent users, number of commits). It is critical to keep the instance registered at all times to prevent it from stopping, so it should be information available instantly. Does not apply to cloud customers as we register these instances permanently.
[REGISTRATION-STATUS]

Information is displayed about the instance registration status:

When instance IS registered
Registered as [INSTANCE TYPE, e.g., dev, preprod, prod] instance by [USERNAME] until [DATE]
[NUMBER] days remaining

_________

[DATE] format is shown as Month (letters) day, year. e.g., "Sep. 15, 2050".

When number of days is 30 or less, the information is highlighted and the following message is displayed instead:
[NUMBER] days remaining. Please contact your project manager or purchase department to prevent service interruption.

[NUMBER] cannot be negative, it is displayed at 0 for past dates.
