[Bug Report] Rule expiry is not honored after suspend and resume

### Describe the bug:
After a rule is created with the duration of X number of hours, and the device goes on standby, the rule remains in effect if the device is resumed after a longer period of time than X.

Include the following information:
- OpenSnitch version: 1.8.0
- OS: Fedora
- OS version: 43
- Window Manager: MATE
- Kernel version: Linux localhost 6.19.14-200.fc43.x86_64 #1 SMP PREEMPT_DYNAMIC Thu Apr 23 17:34:07 UTC 2026 x86_64 GNU/Linux

### To Reproduce:

Steps to reproduce the behavior:
1. Access whatever address that will throw the rule creation request.
2. Set the rule to expire after X many hours.
3. Standby the device.
4. Resume the device after longer than X many hours
5. See that the rule is still in effect

### Post error logs:

### Expected behavior (optional):
The rule expiry should be checked and applied correctly

### Screenshots:

### Additional context:

按照列出的步骤复现该问题，使用 opensnitchd 守护进程，并检查 /var/log/opensnitchd.log 以确认相关行为。首先跟踪规则过期在 standby 和 resume 期间是如何处理的；当为 X 小时创建的规则在恢复运行超过 X 小时后不再生效时，即表示完成。
