Fix: Rename app folder to match app ID

- Renamed analytics-hub/ → analyticshub/
- App ID in info.xml is 'analyticshub' (no hyphen)
- Nextcloud requires folder name to match app ID exactly
- Fixes 'Could not download app analyticshub' error during installation

Installation:
- Upload analyticshub/ folder to /var/www/nextcloud/apps/
- Folder name must match app ID in info.xml

# Weekly Analytics Snapshot - {report_date}
## 📊 Headline
[One sentence summary of the biggest story this week]
## ✅ Key Wins
[2-3 bullet points on positive movements or validations]
## 💡 Recommendation
[One specific action based on the data]
## 📈 The Numbers
[Formatted table of metrics with context]
RULES:
- Be specific (use actual numbers from data)
