Svelte: Remove "See more details" label

[taiyab]

Context

This is our current results summary widget.

We should eliminate the label that says "See more details" to save vertical space. You should only get a notice there once of the conditions are met for an incomplete search, or whatever other states we have for that.

We could also:

• Reduce the left icon size (to 16x16)
• Reduce the size of the caret icon to the right (12x12)

Code Search (Figma)

@taiyab If I understand how we got here correctly, we added the "see more details" because if there was nothing in that space, the page jumps when a search goes from showing a message to showing nothing. I don't think we want the search results to shift when a search completes. Thoughts on how to get around that?
