NutriTrace v1.1.2: OFF search migration, Kilojoules goal fix, barcode scan flow

[thebigjoe1]

Just released. Signed APK + Docker image are up on the release page: https://github.com/TraceApps/nutritrace/releases/tag/v1.1.2

Patch release. Full Open Food Facts integration migration to the two current-canonical endpoints (search-a-licious for text search, v3 for barcode / product detail), a Kilojoules-vs-Calories goal storage cleanup, and smaller UI polish. Six iterative code-review passes on the accumulated dev diff.

Fixed

• Kilojoules goal and Calories goal no longer drift out of sync. Kilojoules was defined as a separately-editable nutrient goal so it stored independently from the Calories goal. Now a display-mode alias for Calories: one canonical source, no drift. One-time migration on next Goals page open handles legacy state. Thanks to @dominicbui for reporting in #146.
• Disabled Calorie Goal Mode buttons look and explain themselves. Dynamic mode requires a connected wearable that reports calorie burn. The disabled state now renders clearly grayed out and a visible helper line under the mode selector explains what's needed. Thanks to @dominicbui for reporting in #147.

Changed

• Barcode scan of an OFF-known product opens the nutrition-facts sheet. Matches the flow when you tap an OFF search result. View nutrition, then Add to Diary or Edit. Unknown-to-OFF barcodes still open the editor directly.
• Open Food Facts search migrated to search-a-licious for better relevance and future-proofing (#133). Text queries hit search.openfoodfacts.org/search, barcode lookups hit /api/v3/product/. Both are the current-canonical endpoints OFF actively recommends. Local OFF mirror is unaffected: proxy still intercepts both URL shapes and the frontend accepts both response envelopes.
• Add-time hydration for OFF foods. search-a-licious deliberately drops serving-size and per-serving fields at index time; NutriTrace now fetches full product detail via v3 the moment you tap an OFF search result. Restores Import Portion As, alt-units picker, and cross-system nutrition-basis warning. Cached in-session per barcode.
• Special characters in user queries no longer break OFF search. Ben & Jerry's, M&M's, Häagen-Dazs etc. get Lucene-escaped before being sent.
