Optimize screen real estate on /publish/datalist

[langswei]

There are a number of ways to tweak the UI for the datalist page in order to get more value out of every pixel, including:

• remove hero (filter block can act as first contentful paint for LCP purposes)
• possibly reduce the # of results using limit param
• remove domain from each listed URL
• round percentages to integer
• consider not rendering text for low percentages which can't fully display the text
• look into reducing whitespace
• evaluate font sizes and general styles in the context of either the new hlx.live documentation style or Spectrum CSS used by other Adobe software

Mostly addressed via #31. Did not look into Spectrum or global style changes. Additional tweaks possible but closing this issue for now.
