fix: clean up files section and add KB/MB unit selector to compress

- Remove duplicate "Files" heading (section header + inline count)
- Space "Show more" and "Clear all" apart on the same row
- Replace bare number input with number + KB/MB dropdown for target
  size, defaulting to KB; MB values are converted to KB for the API
- Hide native number input spin buttons for a cleaner look
