Add MCP media tools, real-time subscriptions, and UI

Major MCP extension: adds tools for media content retrieval, OCR, real-time message subscription with webhook push, chat activity analysis, user profile, and shared file search. Implements persistent subscription management, new prompt templates, and real-time resource endpoints. Updates UI to display active MCP subscriptions, enhances CSV export with MessageID, and documents all new features in the changelog. Removes Dockerfile and docker-compose.yml.
