fix: Make push notifications optional for MIPS compatibility

- Add push-notifications feature flag (enabled by default)
- Make web-push and openssl optional dependencies
- Conditionally compile push notification code
- Disable push notifications for MIPS builds in CI
- Fixes AtomicU64 error on 32-bit MIPS architecture
- x86_64/ARM builds still have full push notification support
