Modifying name validation to allow dashes

[itissdr]

Problem

Routine calls would fail when the database name contains dashes.

Root Cause

The built-in Python isidentifier() function does not follow the same rules as MariaDB identifiers. Python's identifier rules are more restrictive and reject valid MariaDB names containing dashes.

Solution

Added a helper function to validate database names that follows MariaDB's identifier rules instead of Python's.

Changes

• Replaced isidentifier() with custom validation function
• Ensures compatibility with MariaDB naming conventions (allows dashes in identifiers)

Testing

• Tested with database names containing dashes
• Verified backward compatibility with existing valid names
• Existing tests pass (Didnt run the ones requiring gemini api keys)

Example: Database name my-app-db now works correctly instead of being rejected.
