Desktop Sidebar: Remove Unused Icons

[alexrcabral]

Proposed Mockup

The dashboard links should appear below the profile & signout information, as shown in the mockup above. 

Since personalization settings are not currently built out, the unused icons in the sidebar should be removed for now. 

This includes: 

• the TTS / speaker icon
• the STT / microphone icon
• the font size buttons (A-, A+)
• the contrast buttons (Standard/High/Low Contrast)

Buttons to be Removed

Acceptance criteria: 

Given that I'm a user who is on a screen wide enough to view the sidebar, I should encounter the page links beneath the profile and signout information.
