Implement v4.1 web UI refresh #16907
Description
NetBox version
v4.1.0-dev
Feature type
Change to existing functionality
Proposed functionality
Implement a new design for the look-and-feel of the NetBox web UI, incorporating among other elements a theme that spans the side navigation and the main canvas. Prototype images follow; disregard the stylized background motif and substitute a gradient or solid-color background. Also disregard the "netbox labs" and "enterprise" / "cloud" logo elements, substituting the existing NetBox logo.
Use case
Give users a new visual identity that looks nice and doesn't get in their way.
Database changes
None
External dependencies
Possibly font assets
