Fix: SSL pinning, root detection, network resilience, and compile errors

SSL pinning (all 4 apps): IOClient import, subdomain-safe domain matching
Root detection (all 4 apps): modern Magisk/KernelSU/APatch paths
Security checks (rider/driver/admin): PlatformException -> false
Rider crud: 60s timeout, 3 retries, exponential backoff, JWT pre-validation
Driver crud: exponential backoff for TimeoutException
RxInt compile (rider/driver): 10.obs -> RxInt(10)
Admin device_info: add missing imports, fix RxInt, add package_info_plus
