feat: address change with document upload and manual review

[TaprootFreak]

Summary

• Move address change from direct endpoint to KYC flow with document upload and admin approval
• Users submit address proof file via PUT /kyc/data/address/:id, which goes through manual review before the address is updated
• On admin approval, address is written to userData with country validation, transliteration, and Sift update

Changes

• KycChangeAddressData: add file (Base64) and fileName fields
• FileType: add ADDRESS_CHANGE
• KycController: add PUT /kyc/data/address/:id endpoint
• KycService: add updateAddressChangeData() (upload + manual review) and completeAddressChange() (apply address on approval)
• KycAdminService: add ADDRESS_CHANGE case in completion hook
• KycStep: change ADDRESS_CHANGE sessionInfo from NONE to API URL
• UserDataService: add updateUserAddress() with country validation, transliteration, Sift update

Test plan

• Verify PUT /kyc/data/address/:id accepts Base64 file + fileName + address payload
• Verify uploaded file is stored in Azure as AddressChange FileType
• Verify KYC step transitions to MANUAL_REVIEW after upload
• Verify admin approval via PUT /kyc/admin/step/:id triggers address update in userData
• Verify admin rejection sends failure notification
• Verify country validation rejects disabled countries
• Verify Sift billing address update is sent on completion
• Verify build, lint, and format checks pass
