app: parse the Shizuku dumps into link.ra_source and sec.arp_watch

Pure-Kotlin parsers over the captures the battery already makes, tested
against the real archived dumps from both devices - including the
Lenovo's 1000000015 route tables (table ids stay strings), the OnePlus's
stray uid=2000 prefix and mid-line hoplimit, and an ip_monitor that only
ever said EXEC_TIMEOUT. ShizukuProbe now returns three tests; a failed
capture is SKIPPED with its reason so no test type silently vanishes.
