add option to run tests against configured database

- Run development services: `make run`

- Format: `make format`

- Full test suite: `make test`

- Full test suite using the currently configured database connection: `make test TEST_DATABASE=configured`

- Focused Django tests: `JAMA_VAR_DIR=.jama_data uv run jama test rpc`

- Lint one file: `uv run ruff check src/rpc/methods.py`

- Format one file: `uv run ruff format src/rpc/methods.py`

- Build package: `make build`

`make test` runs from `src/` with `JAMA_VAR_DIR=.jama_test_data` and an in-memory SQLite database, then removes `.jama_test_data`. When running tests manually with another `JAMA_VAR_DIR`, remove that generated directory after the test run as well.

`make test` runs from `src/` with `JAMA_VAR_DIR=.jama_test_data` and an in-memory SQLite database, then removes `.jama_test_data`. Set `TEST_DATABASE=configured` to use the database connection loaded from the current `JAMA_VAR_DIR` instead. Django still creates and destroys its usual separate test database. When running tests manually with another generated `JAMA_VAR_DIR`, remove that directory after the test run as well.
