Add server diagnostics to initialize response

serverInfo now includes:
- hostname and ipAddress for server identification
- javaVersion and javaVendor for environment info
- serverStartTime (epoch ms) for uptime calculation
- moquiVersion, runtimePath for deployment verification
- currentUser/currentUserId for auth confirmation

Follows MCP standard - info returned via initialize response
