refactor: remove Claude AI copilot panel — will be replaced with embedded terminal

Gutted the copilot panel, OAuth integration, and AI service registration.
The copilot component files are left in place for future reference but
disconnected from the UI. The replacement will be an embedded local
terminal running `claude` with MCP tools for Wraith session access.
