Fix dashboard crash: trainer_compensations table name + graceful fallback

- Add explicit $table = 'trainer_compensations' to TrainerCompensation
  model (Laravel resolved singular 'trainer_compensation' by default)
- Wrap TrainerDuesWidget query in try/catch so dashboard loads even if
  the compensation migration hasn't been run yet
