fix: dashboard v2 — remove AI味, add demo fallback data

- Remove all emojis from KPI cards, chart titles, AI digest - Change "AI运维助手" to plain "智能运维诊断" - Add realistic demo data fallback when backend offline (no more 0s) - More professional 国企稳重 style Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
