release: 1.3.26 — Watchdog proxy restart protection, WAN monitor debounce, and subscription bootstrap resilience

- Fix #52: Watchdog proxy restart on single URL failure:
  * Validate failure against secondary independent probe URL before declaring proxy down
  * Skip restart when direct WAN is also degraded or down (!direct_ok)
  * Implement 120s cooldown between automated proxy restarts
  * Fix Telegram notification to accurately state 'Перезапуск sing-box' instead of 'Перезапуск роутера'
- Fix #51: Telegram bot spamming WAN up/down notifications:
  * Filter hotplug events strictly by badwan_monitored_interfaces (defaults to wan)
  * Add atomic directory lock with debounce delay and real ubus state query
  * Prevent repeated notifications when interface state has not transitioned
- Feat: 2-VPN deadlock elimination & self-download subscription proxy:
  * Isolate unbootstrapped dependent subscription sections on initial boot (deferred_sections)
  * Allow self-download proxy target for subscriptions with explicit UI hint '(текущее правило при активности)'
  * Enable automatic local proxy fallback for subscription refresh when direct WAN download fails while sing-box is active
  * Add regression test in tests/subscription_bootstrap_deadlock.sh
- Fix: Parental control quota enforcement:
  * Correct route rule filtering when daily quota minutes are exhausted without a fixed time interval
- i18n & Version bump:
  * Bump fe-app-tachyon to 1.3.26 and update Russian PO/POT translations
