feat(application): add inactive profile validation with custom exception

- Create InactiveProfileException for profile active status validation
- Update TriggeringDEXJobBatchCommand to check profile active status before execution
- Add ICfgProfileRepository dependency to batch command handler
- Throw InactiveProfileException when attempting to execute inactive profiles
- Add profile not found validation with descriptive error message
- Reorganize commands under DEXJob/Commands directory structure
