* chore: Extract out accounts test cases from `tests.bats`
Standard test file format, the test cases have been copied over unmodified.
* chore: Revise test case descriptions
* tests(refactor): `accounts.bats`
Revised test cases:
- Some common test case logic extracted to test methods.
- Update direct user management commands to use the `setup email ...` variants.
- Improved assertions.
- Removed `sleep 2` lines as the need for that is ambiguous (may no longer be relevant?)
- Additional commentary for maintaining
- Two test cases for missing `postfix-accounts.cf` opted to just run the image without any volumes instead, as the `without-accounts/` folder was empty anyway. 2nd test case can instead use a single `docker run` to check the newly created`postfix-accounts.cf` content.
- `test/config/without-accounts/` remains as `open_dkim.bats` presently uses it.
* chore: Remove unnecessary account removal assert
Traced this back to the original PR where it appears to have been a typo and was probably intended as a cleanup on the `user4` account. Not necessary, removing.
* chore: Rename `accounts.bat` -> `account_management.bats`
---------
* feedback: Avoid `ls` for detecting directories
Replace `ls -d` approach from original test cases
