- Replace API-based model fetching with direct SQL query on
provider_models table (shared PostgreSQL, no auth needed)
- Frontend: auto-detect base_url from model name when selecting
a Dify model, set provider to 'custom'
- Remove unused requests import and API key fallback logic

- Backend: try DIFY_CHAT/WORKFLOW_API_KEY when workspace key is missing
- Frontend: always show '从 Dify 获取' button, not just after first fetch

- PptSettingsAdmin.vue: full settings page with provider/model/API key
config for PPT extraction, poster copy, and poster image generation
- Backend: GET /insurance/admin/ppt/available-models to fetch models
from Dify API (falls back to builtin list when unavailable)
- LLM client: read model config from SystemSetting DB with 60s cache,
priority: database > environment variables > defaults
- ppt-admin-api.ts: add getAvailableModels() method
