Previous CSS lived in DeckyFleet.css only, so when the form rendered
inside MazeNET Inspector the inputs fell back to browser defaults
(white-on-white, oversized labels, mismatched buttons).
New ServiceConfigForm.css ships with the component itself: small
uppercase tracking-1 labels at 0.6rem (matches kvs .k), dark
transparent inputs with violet focus, matrix-green text inside
inputs, custom select chevron, dedicated svc-cfg-btn that visually
mirrors maze-btn.small, password reveal toggle, and a 96px label
column so labels never wrap into the input. Help text drops to
0.58rem dim under the input. Works identically in both surfaces.
