Issues

This PR introduces dynamic accent color handling and dark mode improvements across the theming system.
Previously, accent colors were resolved manually per component (e.g. via getOrDefault), and UI elements like message bubbles didn’t adapt correctly between light and dark themes.

Causes

• The WireColorSchemeTypes provided static base schemes (LightWireColorScheme, DarkWireColorScheme) without dynamic accent mapping.
• Accent resolution had to be done manually in composables, making theme management inconsistent and error-prone.
• WireColorScheme didn’t yet handle dark/light-specific accent shades for elements like message bubbles.
• The Accent enum lacked a consistent mapping to color swatches.

Solutions

• Introduced a new Accent & Tone system:

  • Added Tone enum (T50–T900) for shade intensity.
  • Added Shades and AccentSwatch models for light/dark accent palettes.
  • Implemented Accent.asSwatch() to resolve the correct palette per theme mode.

• Enabled dynamic accent application in WireTheme:

  • Added LocalWireAccent for providing accent context.
  • WireTheme now applies accents via withAccent(accent) using WireColorScheme.copy().
  • Accent changes automatically trigger recomposition across MaterialTheme components.

• Updated WireColorScheme:

  • Added accent-based colors for self and other message bubbles.
  • Refined tone mapping for primary, highlight, focus, and status colors (error, warning, positive).

• Improved dark mode conversation UI:

  • Adjusted bubble contrast for better readability.
  • Unified accent behavior and tone consistency in chat components.
