release/M4

This is the first release of the UI from this repository (previously found at, the now deprecated, https://github.com/unisonweb/codebase-ui).

The UI changes in this release are subtle, but revolved mainly around our new design system repo (https://github.com/unisonweb/ui-core):

• More consistent layouts
• More consistent colors
• Improve sidebar collapsing
• New "Help and Resources" button
