Drop python 3.10 and update database dependencies

[tieneupin]

Python 3.10 hits end-of-life at the end of this month. SQLAlchemy has also recently started using psycopg as their default dialect when setting up a database connection, which meant that psycopg2-binary was no longer included as part of thje sqlalchemy[postgresql] package set. This breaks things, because we have previously explicitly set up our package to connect to the database using the psycopg2 dialect.

This PR addresses these issues by:

• Updating the Python version range supported by Murfey to 3.11 - 3.14
• Updating the GitHub runners to use Python 3.14 and the test runner range to 3.11 - 3.14
• Updating the database connection URLs in our codebase to let SQLAlchemy decide on the dialect to use
• Pinning the SQLAlchemy version to >=2.1.0, when this change in default dialect was applied
