fix(access): full ground-truth sweep + accurate bootstrap targeting

Browse Source 
access-matrix.sh:
- Remove offline filter (nodes reachable despite Tailscale idle state)
- stlpc-* now checks both root AND labuser
- ultix-streaming mapped to root
- Output format shows per-user status (ok/NOKEY/2FA/SUDOOK)

bootstrap-all.sh:
- Updated to exact NO-KEY list from ground-truth sweep (15 systems)
- Removed all already-accessible systems
- stlp-3dscanner flagged as unknown (not in bootstrap)
