Permission error message not localised for non-English locales

[PujaDeshmukh17]

Describe your changes

Problem:
When a user without upload permissions attempted to attach a file, the error popup always displayed in English regardless of the user's locale:

"You do not have the required permissions to upload attachments. Please contact your administrator for access."

Root Cause:

Hardcoded call site in SDMServiceImpl.java
One specific throw site in the getObject method (403 response branch) used the raw Java constant SDMConstants.USER_NOT_AUTHORISED_ERROR directly, bypassing the SDMUtils.getErrorMessage() lookup that all other throw sites use.

Any documentation
