fix: remove python3-pymysql/reportlab from RPM Requires (not in Rocky 8 repos)

The packages python3-pymysql and python3-reportlab are not available in
Rocky 8 base or EPEL repos. Removed hard Requires and instead:
- Added %post scriptlet that runs pip3 install with fallback warning
- Added %post cockpit restart
- Created /etc/slurmledger/invoices and /var/log/slurmledger dirs
- Documented pip install in %description
