[FeatureRequest] Home Page should have all theportals

[adamfowlerit]

The main page should feature all the portals across all pages for easy access and searching.

We'd still have a sub-page for each section, but the main page should be all of those combined.

Updates should still occur only on the specific pages, so there's no double ups of maintaining records.

The home button could be changed to an admin button since we're low on button space, and the 'Microsoft Portals' title could take you back to the home page instead.

I would like a sitewide search option which might actually fit after the B2B Tenant ID field, anyone want to have a shot at this? @PsychoData @jlaundry @mdjx ?
