feat: add per-component color override parameter (#154)

Add optional `color` parameter to all accent-color-using components:
cv-section, cv-entry, cv-entry-start, cv-entry-continued, cv-honor.

When omitted, behavior is unchanged (uses accent color from metadata).
When provided, overrides accent color for that specific component.

Closes #153
