cyi-box: Memphis-style toolbox admin platform

Go(fun)+SQLite backend, Vue 3 frontend. Modules: dashboard, pay gateway (Epay-compatible + CDK stock), license/card system (per-app appid, domain binding), AI memory bank with built-in MCP server (/mcp, FTS5 search, signed read links), server SSH monitor + terminal + SFTP, proxy pool with protocol-level alive checks, DB manager (mysql/pg/sqlite + SQL autocomplete + import/export), disk share, vault (AES-GCM + TOTP), bookmarks, dev tools.
