Mintlify deploys docs by cloning the repo but does not run `git lfs
pull`. The `.gitattributes` rule `docs/images/** filter=lfs` caused
all doc images to be stored as ~130-byte LFS pointer files, which
Mintlify served as-is — breaking every image on the site.
Removing the LFS rule and re-adding the files as regular git blobs
fixes all images without changing any paths or MDX files.
Also fixes broken Slack link placeholder in troubleshooting page.
