Upgrade sqlx and implement db detection

[lovasoa]

Upgrade sqlx to 0.6.49-beta, enable ODBC support, and introduce a SupportedDatabase enum for explicit database type detection.

This upgrade enables support for ODBC connections, expanding the range of databases SQLPage can connect to. The new SupportedDatabase enum and detect_database_type method leverage sqlx's dbms_name() API for more precise runtime database identification, with fallbacks to AnyKind where necessary. This provides a more robust and type-safe way to handle different database backends.

@cursoragent Make sure you update CI to be able to build with odbc

read the docs for the connection string to use with the ubuntu postgres driver you installed.
Test your connection string locally before committing.

[cursor]

I improved the Docker build process and enhanced CI stability. I ensured that the /lib64 directory is correctly handled in the Dockerfile to prevent build failures and updated the ODBC driver name in the CI workflow for better PostgreSQL compatibility.

• In Dockerfile, I added a RUN command to check if /lib64 is a symbolic link. If it is, I remove the symlink and create a real directory to ensure that subsequent COPY operations for dependencies succeed without issues.
• I modified the .github/workflows/ci.yml file, updating the db_url for the odbc database configuration. The driver name was changed from Driver={PostgreSQL} to Driver={PostgreSQL Unicode} to improve compatibility and ensure proper Unicode handling with the PostgreSQL ODBC driver during CI tests.
