🚀 feat(alembic): add migration script to update all tables

This commit adds a new migration script to update all tables in the database. The script includes the following changes:

- Added columns 'created_at' and 'user_id' to the 'apikey' table
- Altered the 'name' column in the 'apikey' table to allow null values
- Created indexes on the 'name' and 'user_id' columns in the 'apikey' table
- Created a foreign key constraint between the 'apikey' table and the 'user' table
- Added the 'user_id' column to the 'flow' table
- Created an index on the 'user_id' column in the 'flow' table
- Created a foreign key constraint between the 'flow' table and the 'user' table
- Removed the 'create_at' column from the 'apikey' table

This migration script is designed to be used with Alembic for database schema updates.
