Fixed broken "Decisions Over Time" chart that wasn't displaying bars.
Root cause: Empty divs with percentage heights collapsed in flex containers.
Fixes applied:
1. **Pixel heights instead of percentages**
- Calculate absolute pixel heights from h-48 container (192px)
- Percentage heights don't work in flex containers with items-end
2. **Non-breaking space inside bars**
- Added to prevent empty div collapse
- Even with height set, empty divs can collapse in some layouts
3. **Decision count labels**
- Display count above each bar for exact numbers
- Shows both visual proportion (bar height) and exact value (label)
4. **Minimum 10px height**
- Ensures small values are always visible
- Prevents bars from disappearing for low counts
5. **Wider bars**
- Changed from max-w-16 (64px) to w-3/4 (75% width)
- More visible and easier to interact with
Timeline modes working:
- ✅ 6-Hourly (24h) - 4 bars showing last 24 hours in 6-hour buckets
- ✅ Daily (7d) - 7 bars showing last 7 days
- ✅ Weekly (4w) - 4 bars showing last 4 weeks
All modes show current snapshot updated on refresh.
Files changed:
- public/js/admin/audit-analytics.js: Timeline rendering logic
- public/admin/audit-analytics.html: Updated cache version
- public/*.html: Cache version bump for consistency
