feat: add api key auth, devii agent, openai gateway, and admin service management

This commit introduces a comprehensive set of new features including API key authentication with CLI management commands (get, reset, backfill), a Devii agentic assistant with WebSocket terminal and session bootstrap, an OpenAI-compatible LLM gateway service, and an admin service management panel. It also adds Playwright browser automation for bot support, configures internal gateway URLs, refactors content editing/deletion to support JSON API responses, and updates documentation across AGENTS.md, README.md, and the developer docs site.
