Modernize the UI and fix the equalizer sizing bug

Bug fix

- EqualizerIcon: the SVG was rendering at the wrong size (filling
  its parent) because it had no explicit width/height attributes.
  Now it accepts a size prop with a 24px default and the SVG element
  carries the size as width/height attributes, with the className
  on top. Can't accidentally balloon.

Design

- Stripped the light-mode CSS — the app is dark-only now, and the
  theme toggle was a no-op (clicking it just toggled a class that
  had no matching rules). ThemeToggle.tsx and lib/theme.ts are
  gone; initTheme() call removed from main.tsx.

- Reworked the input form:
    • brand row is now small + refined (icon + wordmark, no huge
      gradient title)
    • Options is a single subtle collapsible card with a chevron and
      a count badge showing how many options are non-default
    • Vocals is now a segmented pill (single rounded container, two
      flat segments) instead of two full-width grid buttons
    • Generate button is slightly smaller (py-3.5, text-sm) and
      uses a softer shadow (shadow-violet-900/20)

- Empty state in the results panel: dashed-border card, soft
  gradient blur behind the music icon, cleaner copy.

- Results header: smaller heading, the 'Regenerate All' and
  'Cancel' buttons are now tiny ghost-style pills in the top-right.

- Sticky ZIP bar: softer shadow, more refined copy.

- Result cards: smaller icon, single-line title, the Regenerate
  button is now an inline pill that fits next to Revert + Copy.

- Home page header now has a tiny equalizer icon + 'MelodyMuse'
  wordmark on the left (was just text). Settings page header has
  the back arrow on the left and the title, no theme toggle.

- Global CSS: added modern focus-visible ring, custom selection
  color, subtle scrollbar thumb, slightly tweaked the gradient
  text to a softer violet-300 → cyan-300 instead of the loud
  violet-400 → fuchsia-400 → cyan-400.
