Phil Skentelbery d565721cdb fix: Add data transformer to resolve metrics dashboard template mismatch ...

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
