Major documentation restructure - consolidated docs

New Structure:
- 01-NETWORK-MAP.md - Network topology, IPs, Docker networks, services
- 02-SERVICES-CRITICAL.md - DNS, Auth, Routing (P0/P1 services)
- 03-SERVICES-OTHER.md - All non-critical services
- 04-HARDWARE-INVENTORY.md - Physical devices and specs
- 05-CHANGELOG.md - Major events only

New Folders:
- docs/archive/ - Legacy docs (read-only reference)
- docs/wip/ - Planned changes and ideas
  - UPGRADE-2026-HARDWARE.md - N5 Air + N100 migration plan
  - GITOPS-CONTAINERS.md - Phase 2 container GitOps

Changes:
- Moved all 22 legacy docs to archive/
- Consolidated container IPs, physical map, and services into single network map
- Extracted critical vs non-critical service classification
- Simplified changelog to major events only
