Add state to MCP profile and refactor contract filter

Add the profile state attribute (ACTIVE/INACTIVE) to the MCP
Profile schema so listUsers and getUser tools expose it, and
add a state filter to listUsers.

Rename excludeContractEnded to contractEnded across the entire
stack (MCP, GraphQL, CLI, frontend). The new boolean is two-way:
true returns only users with ended contracts, false returns only
users with active or no contract, and null returns all.
