Add JARVIS improvements: mobile UI, sparklines, suggestions, multi-step commands, Arc Reactor health, tier badges

- Mobile UI: 3-button bottom nav with panel switcher
- Chat history search: search modal with keyword query
- News filtering: category filter with localStorage persistence
- Proactive reminders: planner/appointment alerts at login and every 5 min
- Proactive alerts: polls every 60s, speaks new critical/warning alerts
- Agent sparklines: 2h CPU+MEM sparkline on each online agent card
- Tier source badge: KB/GROQ/CLAUDE/OLLAMA pill shown after each reply
- VM suggestions: 24h resource analysis via voice command
- HA scene control: fuzzy-match scene activation via voice
- Jellyfin control: pause/stop/next/previous via voice and KB
- Pattern suggestions: usage_patterns table + proactive chips every 30 min
- Multi-step commands: compound "X and Y" command parsing (Tier 0.5)
- Arc Reactor health: warning=amber/1.2s, critical=red/0.6s pulse encoding
- Cross-session history: last 6 turns loaded from prior session
- Restart agent: voice command to restart any JARVIS agent
- New endpoints: history.php, metrics.php, suggestions.php, jellyfin.php
