Fix most deprecation warnings for Python 3.12 compatibility

[m1yag1]

Summary

This PR aims to reduce the number of deprecation warnings when running the test suite.

Changes

• Upgrade Sentry SDK from 1.0.0 to 2.37.1 to resolve deprecated datetime functions
• Change aiohttp HTTPException from return to raise pattern
• Fix Docker PostgreSQL connection configuration for tests (this was primarily for my setup as I had a port conflict w/ pylance on vscode)
• Document SQLAlchemy limitation due to asyncpgsa compatibility

Only two left!
