fix: Resolve ESLint errors to enable production build

- Remove unused getCategoryColor import from Charts.tsx (no-unused-vars)
- Remove unused CardDescription import from HomePage.tsx (no-unused-vars)
- Fix CardTitle type annotation (HTMLParagraphElement -> HTMLHeadingElement)
- Add eslint-disable-next-line for CardTitle heading-has-content (intentional generic wrapper component)

Build now compiles without errors.
