P14-02: Split warps into guest FRONT and staff BACK service warp (A08)

The FRONT Mana warp is guest-only: its connectors carry the "!staff" access,
which path access checks treat as open to everyone except staff. A new 2x2
BACK service warp links only to other service warps for staff, with A07
values. Registry and palette now hold 25 definitions.
