Fixed import sql ignoring multiple tables in a ddl file

[joe-albert]

There was an issue I noticed where when a sql ddl file had multiple tables defined the import functionality would only convert the first one to ODCS and ignore the rest.

Also, a few mysql types were not handled so I added handling for those.

Edit: sorry made a few other changes to accommodate primary keys defined at the table level.

• Tests pass (uv run pytest) [I ran relevant tests and they passed-- I do not have docker setup locally so did not run the full suite, also did not see any documentation on this part of the testing?]
• Code formatted (uv run ruff check --fix && uv run ruff format)
• README.md updated (if relevant)
• CHANGELOG.md entry added

This is a test sql ddl I used where only the first table was processed:

CREATE TABLE customers (
  id INT(10) UNSIGNED NOT NULL AUTO_INCREMENT COMMENT 'Primary key, unique customer identifier',
  first_name VARCHAR(50) NOT NULL COMMENT 'Customer first name',
  last_name VARCHAR(50) NOT NULL COMMENT 'Customer last name',
  email VARCHAR(255) NOT NULL COMMENT 'Customer email address, used for login',
  phone VARCHAR(20) COMMENT 'Optional contact phone number',
  date_of_birth DATE COMMENT 'Customer date of birth',
  is_active TINYINT(1) UNSIGNED NOT NULL DEFAULT 1 COMMENT 'Whether the customer account is active',
  created_at DATETIME NOT NULL COMMENT 'Timestamp when the record was created',
  updated_at DATETIME COMMENT 'Timestamp when the record was last updated',
  PRIMARY KEY (id),
  UNIQUE KEY customers_email_uk (email)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

CREATE TABLE orders (
  id INT(10) UNSIGNED NOT NULL AUTO_INCREMENT COMMENT 'Primary key, unique order identifier',
  customer_id INT(10) UNSIGNED NOT NULL COMMENT 'Foreign key referencing the customer who placed the order',
  status VARCHAR(20) NOT NULL DEFAULT 'pending' COMMENT 'Order status: pending, processing, shipped, delivered, cancelled',
  total_amount DECIMAL(10,2) NOT NULL COMMENT 'Total monetary value of the order',
  item_count SMALLINT UNSIGNED NOT NULL COMMENT 'Number of items in the order',
  notes VARCHAR(1000) COMMENT 'Optional free-text notes about the order',
  shipped_at DATETIME COMMENT 'Timestamp when the order was shipped',
  created_at DATETIME NOT NULL COMMENT 'Timestamp when the order was placed',
  updated_at DATETIME COMMENT 'Timestamp when the record was last updated',
  PRIMARY KEY (id),
  KEY orders_customer_id_idx (customer_id),
  CONSTRAINT orders_customer_fk FOREIGN KEY (customer_id) REFERENCES customers (id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

The changes LGTM! Can you add tests or extend an existing test to cover the bugs you described (multiple tables & composite keys)?
