Replace Alembic with plain SQL schema

- Fix scalar_first() bug in persistent_conversation.py (use scalars().first()) - Add schema.sql with all 7 tables (users, user_preferences, user_facts, guilds, guild_members, conversations, messages) - Update database.py to run schema.sql on startup - Remove Alembic directory and configuration - Remove alembic from requirements.txt
