revalidatePath was causing the server component to re-render and
potentially remount the client component, resetting all useState values.
Since the client component already updates its local state optimistically
after save, revalidatePath is unnecessary here. Also uninstalls agentation.

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.
