Add more options to customize tooltip:

- For the "Text Style" options, currently there is only a text renderer option for each column. We will change to this:
    - Rename title "Text Style" to "Column Styles"
    - Add a dropdown with "Hidden", "Minified", and "Full" to allow customizing how each column is displayed in the tooltip.
    - When the display type is image, have a option to set the image size.
- In settings panel, remove the "Tooltip" dropdown --- it's superseded by above.
- For the search result box, use the same component as the tooltip, for consistency.

Minor fixes and styling adjustments:
- Clicking the nearest neighbor in search result should trigger the tooltip (just like clicking a row in the table)
- Add a little bit of transparency and background blur for tooltip and legend.
