feat(import): add import-only option for recipes without downloading missing LoRAs

Add dual-button design in recipe import flow:
- Details step: [Import Recipe Only] [Import & Download]
- Location step: [Back] [Import & Download] (removed redundant Import Only)

Changes:
- templates/components/import_modal.html: Add secondary button for import-only
- static/js/managers/ImportManager.js: Add saveRecipeOnlyFromDetails() method
- static/js/managers/import/RecipeDataManager.js: Update button state management
- static/js/managers/import/DownloadManager.js: Support skipDownload flag
- locales/*.json: Complete all translation TODOs

Closes #868
