feat: add theme-aware chart colors for dark/light mode support

Replace hardcoded dark-theme hex colors in recharts components
(tooltips, axes) with a useChartTheme hook that reads the current
theme from ThemeContext. Charts now render correctly in both light
and dark mode.

Closes leeworks-agents/SPARC#1324
