Add attendance history in shift details modal

[SanjayaGrg]

Summary

This PR adds attendance history display in the shift detail screen and shift detail modal.

Changes made

• added local attendance history display in ShiftDetailsScreen
• added local attendance history display in ShiftDetailsModal
• used AsyncStorage attendance data based on shift id
• kept attendance data available even when shift status changes
• added fallback local check-in/check-out handling while backend attendance API is not ready

Notes

• attendance is currently shown from local storage only
• backend attendance API is not used yet
• this is temporary until attendance endpoints are ready

Testing

• checked in locally and confirmed check-in time is saved
• opened shift details screen and verified attendance history is shown
• opened shift details modal and verified attendance history is shown there too
• confirmed attendance still shows when the same shift moves by status and keeps the same id

Thanks for adding the attendance history — this looks useful.

Just a note: the check-in/check-out issue has already been resolved, so we shouldn’t be modifying or commenting out that logic in this PR.

Could you please:

• Revert any changes related to check-in/check-out
• Keep this PR focused only on displaying the attendance history in the shift details screen/modal

check-in/check-out issue is already been solved.
