fix: Prevent TypeError crash on undefined attachment info

Adds optional chaining to info.filename in AttachmentList.vue. This prevents a complete UI crash (TypeError: Cannot read properties of undefined (reading 'filename')) when rendering a card that has an attachment with missing or undefined info data.
the attachment list was not getting populated on some cards
