docs: add migration system documentation and generated initial migrations

Added `README.md` to document the database migration system, including generation and usage instructions. Updated `generate-migrations.ts` to fix directory structure and streamline commands. Included initial migration files for schema setup using DrizzleORM.

+# Database Migrations
+
+This directory contains the migration system for the database. The migrations are generated using DrizzleORM and are stored in the `sql` subdirectory.
+
+## Directory Structure
+
+- `sql/` - Contains the generated SQL migration files
+- `generate-migrations.ts` - Script to generate migration files
+- `migrate.ts` - Script to run migrations
+- `README.md` - This file
+
+## How to Use
+
+### Generating Migrations
+
+To generate migrations based on changes to the schema, run:
+
+```bash
+npm run db:generate:ts
+```
+
+This will generate SQL migration files in the `sql` directory.
+
+### Running Migrations
+
+To run all pending migrations, run:
+
+```bash
+npm run db:migrate
+```
+
+### Generating and Running Migrations in One Step
+
+To generate and run migrations in one step, run:
+
+```bash
+npm run db:update
+```
+
+## Integration with NestJS
+
+The migrations are automatically run when the application starts. This is configured in the `DatabaseService` class in `src/database/database.service.ts`.
+
+## Migration Files
+
+Migration files are SQL files that contain the SQL statements to create, alter, or drop database objects. They are named with a timestamp and a description, e.g. `0000_lively_tiger_shark.sql`.
+
+## Configuration
+
+The migration system is configured in `drizzle.config.ts` at the root of the project. This file specifies:
+
+- The schema file to use for generating migrations
+- The output directory for migration files
+- The database dialect and credentials
