Transform meetings page into context page with tabs

Add structured organization context with 5 markdown sections (Product, Architecture, Team, Processes, Customers) editable inline. Meetings are now a tab within the context page. Moved all GraphQL queries from hooks/graph/MeetingGraph.ts into colocated components following new best practices. Updated database schema, backend services, GraphQL resolvers, and MCP API to support the new context fields and structure.
