feat(netbox)!: gut server from 182 to 37 tools

BREAKING CHANGE: Removed circuits, tenancy, VPN, wireless modules entirely.
Stripped DCIM, IPAM, virtualization, extras to only essential tools.
Deleted NETBOX_ENABLED_MODULES filtering — no longer needed.

- Delete circuits.py, tenancy.py, vpn.py, wireless.py
- Strip dcim.py to sites, devices, interfaces only (11 tools)
- Strip ipam.py to IPs, prefixes, services only (10 tools)
- Strip virtualization.py to clusters, VMs, VM interfaces only (10 tools)
- Strip extras.py to tags, journal entries only (6 tools)
- Remove all module filtering code from config.py and server.py
- Rewrite README.md with accurate 37-tool documentation
- Update CHANGELOG.md with breaking change entry
- Token reduction: ~19,810 → ~3,700 (~81%)

Remaining work: Update cmdb-assistant plugin skills (10 files) in follow-up PR
