feat: OS Share Target for recipe URLs (v0.67.0)

Declares share_target in manifest.ts (action /recipes, GET,
title/text/url params). recipes/page.tsx extracts the shared link --
preferring the url param, falling back to the first http(s) URL
found inside text since senders vary on where they put it -- and
passes it to RecipesHeader as sharedUrl. UrlImportDialog gained
initialUrl/autoImport props so the existing import-from-URL flow
opens pre-filled and fires immediately instead of requiring the user
to paste the link back in.

Chromium/Android only -- Safari has no Share Target API at all,
same restriction already documented for the install-prompt banner.
