[Feat]: Add `last seen` attribute from node on Centralized Admin Interfaces Node management tables

[hugovalente-pm]

Problem

When trying to dig through Offline nodes it is very difficult to understand if a node is Offline for a long period of time (days, weeks, months) or if it is Offline due to a recent outage.

Description

We want to provide the users with an extra column on Centralized Admin Interface Node management tables so they can, at least, use it as a sorting mechanism.

NOTE: This column should not display a timestamp but a relative time, e.g.:

• <1 min.
• X min.
• X day(s)
• X week(s)

Importance

must have

Value proposition

1. With a click on the sorting of the Last seen column users can easily check which nodes have been connected recently
