feat(mcp): add stats, value props, and CTA tools for landing pages

Implements three new MCP tools for landing page management: update_landing_stats for stat counters, update_landing_value_props for value proposition cards, and update_landing_cta for bottom call-to-action section. Each tool supports structured data with validation and integrates with existing config save flow.
