Fix team scope when syncing role models

[amrachraf6699]

Summary

Fixes Role::syncModels() removing role assignments from every team when teams are enabled.

The pivot delete query is now scoped to the active permissions team, matching the behavior of the user-side role synchronization APIs.

Problem

Calling:

setPermissionsTeamId(1);

$role->syncModels([]);

previously deleted all assignments for that role, including assignments belonging to other teams.

Fix

Adds the active team constraint to the inverse role-model pivot query used by syncModels().

Tests

Added a regression test confirming that syncing models in team 1 removes only team 1’s assignment and preserves the same role assignment in team 2.

vendor/bin/pest tests/Traits/HasAssignedModelsTest.php --filter="only syncs models for the active team"

Passed.
