watchdogs: add echo banners to network/storage/stability

All watchdog scripts now open with a consistent echo banner:
  ━━━ <icon> <Name> Watchdog — <timestamp> ━━━

Previously network and storage used a quiet log() line (no separator),
and stability_watchdog used warn() which made every run show ⚠️.

Also: network_watchdog now logs "Network healthy ✅" on clean exit,
and stability_watchdog's reboot-trigger block now says "Stability"
instead of the old "System Watchdog" label.
