Page attachment validator

Sometimes, page attachments are displayed on a Confluence page as a broken image. This can mean that the attachment is either:

• Missing or corrupt within the Attachments folder or
• Are stored in a location on the file system that's different from what Confluence is expecting based on the file's metadata stored within the CONTENT table.

It would be proactive to have a way to determine if attachments are missing or corrupt or not residing on an expected file path and then contain the results as part of the healthcheck. For the latter condition, users could then follow the steps outlined in How to resolve missing attachments in Confluence.
