fix: photo import language + no-recipe-recognized handling (v0.29.0)

importFromPhoto() accepted a locale param but silently discarded it
(named _locale, never read) — now builds a language instruction the
same way generate-recipe.ts does for text generation.

The AI output schema had no way to signal "couldn't find a recipe in
this image" — generateObject would always fabricate a title/fields.
Added a `found` boolean the model sets to false in that case; the
route now returns 422 instead of creating a garbage recipe and
sending the user into the editor with it.

+### Added
+- **Photo recipe import now respects your app language** — previously it defaulted to English (or whatever language was in the photo) instead of matching your locale like other AI generation features.
+
+### Fixed
+- Importing a photo with no recognizable recipe used to open the recipe editor anyway with empty/garbage fields — it now shows a clear error instead.
