feat(console): rehauled navigation for instances including breadcrumb (#10283)

This PR significantly improves user navigation by introducing a new
instance-level navigation bar. This new bar, positioned above the
existing organization navigation, provides quick access to key sections:
Home, Organizations, Actions, and Settings.

Additionally, the breadcrumb component has been refined for more
consistent behavior, reintroducing intuitive breadcrumb buttons to
easily navigate up the hierarchy. These changes also include design
improvements for a cleaner and more streamlined appearance across the
interface.
