Restyle UI with neon/terminal "hackertyper" theme

Darker phosphor-black background with ambient neon vignette, monospace
everywhere, glowing neon-green accents, and CRT scanline + brand-flicker
effects. Restyle only — every class name HTML/app.js depends on is
preserved (status pills, fec-cell, slot-arrow, table classes, etc.).

- Neon-green primary / cyan secondary / magenta-red danger, all with
  text-shadow + box-shadow glow
- Glowing focus rings on inputs, glowing buttons and selected rows
- CRT scanline overlay (body::after, non-interactive) + subtle flicker
- Neon scrollbars and selection highlight

Verified by rendering the login view offscreen via Electron.
