Root cause: Template expects flat structure (metrics.database.count) but
monitoring module provides nested structure (metrics.by_type.database.count)
with different field names (avg_duration_ms vs avg).
Solution: Route Adapter Pattern - transformer function maps data structure
at presentation layer.
Changes:
- Add transform_metrics_for_template() function to admin.py
- Update metrics_dashboard() route to use transformer
- Provide safe defaults for missing/empty metrics data
- Handle all operation types: database, http, render
Testing: All 32 admin route tests passing
Documentation:
- Updated implementation report with actual fix details
- Created consolidated hotfix design documentation
- Architectural review by architect (approved with minor concerns)
Technical debt: Adapter layer should be replaced with proper data
contracts in v1.2.0

CRITICAL production hotfix for v1.1.1-rc.2 addressing route conflict
that caused 500 errors on /admin/dashboard.

- Renamed metrics dashboard route from /admin/dashboard to /admin/metrics-dashboard
- Added defensive imports for missing monitoring module with graceful fallback
- Updated version to 1.1.1-rc.2
- Updated CHANGELOG with hotfix details
- Created implementation report in docs/reports/
Testing:
- All 32 admin route tests pass (100%)
- 593/600 total tests pass (7 pre-existing failures unrelated to hotfix)
- Verified backward compatibility maintained
Design:
- Follows ADR-022 architecture decision
- Implements design from docs/design/hotfix-v1.1.1-rc2-route-conflict.md
- No breaking changes - all existing url_for() calls work correctly
Production Impact:
- Resolves 500 error at /admin/dashboard
- Notes dashboard remains at /admin/ (unchanged)
- Metrics dashboard now at /admin/metrics-dashboard
- Graceful degradation when monitoring module unavailable
