feat: add ShareServer console prototype

ShareServer previously existed only as design documents. The repository now includes a standalone Hono service and a responsive React management-console prototype covering administrator and member workflows, with local build, test, and container entry points.

The sharing design now includes organization-scoped digital agents and explicit local partitioned-memory selection for @ calls. Memory documentation consistently uses partitioned memory and treats time or internal events only as optional recall triggers.

This remains an interactive prototype: fixture actions do not persist, and production authentication, PostgreSQL isolation, device connections, routing, relay, and federation still require implementation.

Release note: 新增可独立运行的 ShareServer 管理控制台交互原型，并完善组织数字人与分区记忆共享设计；当前原型数据和操作不会写入生产系统。
