feat: multi-gateway profile support, provider management overhaul, and model settings tab

- Profile-aware proxy: inject API key from profile-specific .env, route requests via X-Hermes-Profile header
- Remove auth.json dependency: built-in providers use .env, custom providers use config.yaml
- Add allProviders field to available-models response with all hardcoded provider catalogs
- Add Models tab in Settings for editing provider API keys (built-in → .env, custom → config.yaml)
- Add PUT /api/config/providers/:poolKey for updating provider credentials
- ProviderFormModal uses backend allProviders for preset dropdown
- Gateway log format support: parse both agent and gateway log formats
- Add webui server.log to log viewer with log rotation at 3MB
- Fix provider delete loading state and OAuth provider cleanup
- Setup script: require Node.js 23+, auto-upgrade if version too low
