Subject: [PATCH] feat(admin-auth): add dev-only QR bypass via
 ?devBypassAdmin=true

Fabricates a local admin session and activates it directly, skipping the
Telegram QR flow, for local testing without a reachable session backend.
Guarded by environment.production at runtime - no-ops in production
builds even if this code ships.
