Add full REST API for all deployment operations (projects, servers, docker)

Port all IPC handlers to HTTP endpoints so the UI and LLM use the same
API. Adds routes/projects.js (scan, compare, init), routes/servers.js
(CRUD, containers, logs), routes/docker.js (build, deploy, pull, vscode-diff).
Enhanced ssh.js with full SSHService class (SFTP upload/download).
Updated renderer api.js to use fetch instead of window.api IPC.
Added concurrently for npm run dev (API + Vite + Electron).
OpenAPI spec now covers all 24 endpoints.
