Add boot timing and AVB/Play Integrity evasion

Boot timing system defers all modifications until after Play
Integrity first attestation completes. Monitors DroidGuard
(com.google.android.gms.unstable) CPU activity to detect
attestation window. PI watcher daemon auto-hides mods during
periodic re-checks — unmounts spoofs, removes non-stock props,
ensures boot state reads green/locked/enforcing, then re-applies
after check finishes. post-fs-data.sh cleaned to only set
stock-safe props during early boot. KernelSU version props
hidden. WebUI boot timing panel with hide/unhide controls.

# Boot Timing & Verification Evasion
#
# Controls WHEN custom drivers and modifications are applied relative
# to Android's verification checkpoints:
#
# 1. AVB (Android Verified Boot) — bootloader, before kernel
# KernelSU handles this. We don't touch partitions. PASS.
#
# 2. dm-verity — block-level hash verification
# KernelSU overlays are above dm-verity. Stock blocks untouched. PASS.
#
# 3. Play Integrity / SafetyNet — after boot, runs in GMS process
# This is what we need to time around. First check is ~10-30s
# after boot_completed. Periodic re-checks every few hours.
#
# 4. Banking apps / root detectors — check on app launch
# These read props, scan /proc, check mount points.
#
# Strategy:
# - post-fs-data: ONLY stock-safe props. No mods. No spoofs.
# - boot_completed: Wait for first PI attestation to finish
# - Apply mods AFTER attestation window closes
# - Run a watcher that detects PI re-checks and temporarily
# unmounts spoofs + restores stock props during the check
