VSN-2813/ feat(driver-absence): add 48h rule for absence declaration and justification tracking

Changes :

• Add 48h working-hours validation for mobile declarations (APPLICATION reception mode): blocks creation if absence starts within 48 working hours, forces phone call instead
• Add cron job to automatically mark absences as NOT_JUSTIFIED + CANCELLED when no justification document is provided within 48h of creation
• Fix LEAVE request validation in updateDriverAbsence and updateDriverAbsenceByUuid to allow absenceMotif as an alternative to leaveType
• Include CANCELLED status in the processed absences endpoint
• Map justificationStatus and supportingDocumentUuid in DriverAbsenceMapper.toDto
• Fix hydrateJustificationFileUrl to skip document lookup when supportingDocumentId is 0 or null
