feat: add AI cost tracking for social publisher content and hashtag generation

Pass user_id, company_id, and feature name to generate_text() calls:
- 'social_publisher_content' for post content generation
- 'social_publisher_hashtags' for hashtag generation
All costs logged to AIUsageLog and AIAPICostLog with user/company context.
