feat: add Synology NAS, Home Assistant monitoring, multi-channel notifications
New tabs: - Synology NAS: CPU, RAM, temp, volumes, VMs, Docker containers - Home Assistant: sensors, automations, persons, climate, battery, doors New features: - Personalized PC agent download with custom name - Notification settings: per-category Telegram/Email/WhatsApp toggles - Email via SMTP, WhatsApp via CallMeBot API - Test notification buttons for each channel - Unified notifier replaces direct Telegram calls in alerter Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
