HYBRID CORE 5.1.0-0922 — ACCESS FIX 0923-01 (URGENT, NO CROSS-BOARD ACCESS)

- Non-admin staff can no longer open Core pages (registry, network, receivers, connections, settings, control), even with the Perfex "Manage Hybrid Core" capability.
- Non-admins can open Board Edit and change member functions only for Boards where they are an active member with Edit, or their sub-Boards. Board settings (parent, Receiver, services) stay administrator-only.
- Nobody can change their own Board permissions.
- Board View for non-admins redirects to the scoped Hybrid Boards workspace (Core Board View was not territory/assignment scoped).
- HR admin pages (URLs starting hybrid_hr) are administrator-only; staff use HR in the Board Operations tab. Prefix list: option hybrid_core_admin_only_modules (comma-separated); set to "-" to disable.
- No schema change; schema version unchanged.
