Modernize card and player visuals

[hellcat707hp]

Details

We want clean up/modernize some the visuals in the app. Notably, making the station and grouping cars closer to a Material card and adjusting the actively-playing footer to be less chunky feeling.

Goals

• Make grouping and station cards more in line with Material design. Appearance should be near or match a Material card. Flexibility is afforded on elevated, flat, or outline depending on what looks best.
  • We might also attempt to address station names truncating too early (like VIBE on GTA4). If not, please spin off into a new issue.
• Rework now-playing footer with better design
  • Utilize more modern icons for player controls and placeholder image. Preferably Material design icons.
  • Include the station grouping in the description (sort of like an Album name?)
    • Investigate if this is reasonable to carry over into the audio data for display elsewhere.
