[Draft] Enable psycopg v3 tests

[kwongtn]

Description

Merge the following first:

• Update test scope to include django 5.1, update pre-commit hooks #683
• test: Replace django mptt with django tree queries for tests #684

P.s. Not sure if putting like 50 test scenarios is a good idea though 😅

Also I was thinking -- are we even using postgres in tests? 🤔
