feat(demo): migrate 5 SelfStack services to demo stack (16→24 services)

Add Reactive Resume, Metrics, Kiwix, Resume Matcher, and Apple Health
from the earlier SelfStack project. Rewrite Apple Health collector to
use InfluxDB v2 with proper error handling. Update all tests, scripts,
Homepage config, env template, and documentation for the expanded stack.

New services:
- Reactive Resume (4016) + Postgres/Minio/Chrome companions
- Metrics (4021) - GitHub metrics visualization
- Kiwix (4022) - offline wiki reader
- Resume Matcher (4023) - AI resume screening
- Apple Health (4024) - health data collector → InfluxDB v2

Also adds git policy to AGENTS.md: always commit and push automatically.
