feat: add comprehensive OpenCode API endpoint proxies

Added proxy routes for all OpenCode internal API endpoints to support
full application functionality when accessed via session manager:
- project, agent, config, model endpoints
- thread, chat, conversation endpoints
- command, mcp, lsp, vcs endpoints
- permission, question, event, status endpoints
- internal session endpoint (distinct from container sessions)

Also updated Caddyfile for routing configuration.
