Fixes Facebook fallback and shared-post attachments so they render as clickable links in conversations. Closes: - https://github.com/chatwoot/chatwoot/issues/4767 - https://github.com/chatwoot/chatwoot/issues/5327 Why: Facebook can send shared links as `fallback` attachments with a top-level `url`, and shared posts as `share` attachments with the URL under `payload.url`. The current flow either misses the nested URL or treats `share` as downloadable media, so these messages do not render correctly. What changed: - Store Facebook fallback URLs from either `attachment.url` or `attachment.payload.url`. - Treat Facebook `share` attachments as fallback link attachments instead of downloading them as files. - Render fallback attachments in the next message bubble UI as clickable links. How to test: 1. Connect a Facebook inbox. 2. Send a shared link to the page. 3. Send/share a Facebook post to the page. 4. Open the conversation in Chatwoot. 5. Confirm both messages appear as clickable link bubbles. Co-authored-by: Muhsin Keloth <muhsinkeramam@gmail.com>
