URGENT FIX: Admin form was not properly saving AI provider configuration,
causing 'AI_PROVIDER_TAGS is not configured' error even after setting OpenAI.
Changes:
- admin-settings-form.tsx: Added validation and error handling
- admin-settings.ts: Filter empty values before saving to DB
- setup-openai.ts: Script to initialize OpenAI as default provider
This fixes the critical bug where users couldn't use the app after
configuring OpenAI in the admin interface.
