* Handle composite IntFlag.name on Python < 3.11
On Python < 3.11, IntFlag.name returns None for composite flags
(e.g. NotificationFlag(0x000900) = SOFTWARE_PRESENT|WIRELESS).
The previous fix (#3184) returns an empty list in this case, losing
the flag names. This commit decomposes composite flags manually by
iterating over enum members, producing correct results on all
supported Python versions (>= 3.8 as declared in setup.py).
Add regression tests covering composite flags and None input.
Tested on:
- Python 3.9.2 (Debian 11): 56/56 passed
- Python 3.11.15 (pyenv): 56/56 passed
