[CW-4330](https://linear.app/chatwoot/issue/CW-4330/bug-attachments-in-gallery-view-gets-duplicated-when-you-navigate-back)
**Cause**
When navigating back to a previously viewed conversation, attachments
were being duplicated in the Gallery View. This occurred because the
`SET_ALL_ATTACHMENTS` mutation was appending new attachments to existing
ones `(attachments.push(...data))` instead of replacing them. Each time
a user returned to a conversation, the attachment list would grow,
showing duplicate images.
**Solution**
Updated the `SET_ALL_ATTACHMENTS` mutation to replace the entire
attachments array instead of appending to it. This change ensures
attachments are cleared before adding new ones when returning to a
previously viewed conversation, preventing duplicates.
