style: align advanced settings rows

The advanced settings labels (num_keep, num_predict, top_k, ...) had
variable widths, so each numeric input started at a different x
position. Give the labels a fixed 150px width in the #advanced-fields
rows so all inputs line up in a single column.

Verified in a live DOM: after the rule applies, all 10 labels share the
same width (150px) and all 10 inputs start at the same x position.
Results: 73 passed, 0 failed. dist rebuilt.
