Andrey Antukh 60b3ac25f4 ♻️ Rename unfurl to link-preview and harden preview endpoint
Rename the whole feature from unfurl to link-preview: handler namespace, template, /link-preview route, :link-preview flag, nginx variable and docs page. Make the flag opt-in by removing it from the default flags. Serve file-thumbnail objects with full public semantics while the flag is on, restrict the route to GET/HEAD, make a present file-id decisive over project/team context, preserve the query string on the human redirect and skip no-op replaceState writes. Cover the new behavior with backend and frontend tests.
