system-locked violation types (alpha & terlambat) + proporsional poin alpha per jam
- Migration: add is_system column to violation_types, mark alpha & terlambat - DestroyType guard: system types cannot be deleted - UpdateType guard: slug tetap walau nama diubah untuk system types - UI: delete button hidden, badge lock untuk system types - Seeder: ViolationTypeDefaultsSeeder untuk fresh deploy - AttendanceController: lookup by slug (alpha/terlambat) instead of fuzzy match - Alpha auto-violation: poin proporsional per jam (round((points/10)*count), min 1) - Terlambat auto-violation: poin fix sesuai jenis (2 poin) - Also handles both A (alpha) and T (terlambat) statuses for auto-violations
