feat: fruit overview with thumbnails and card layout (story #07 )

- Auto-crop thumbnails on image upload (Go stdlib, no external deps): find non-background bounding box, pad 5px, scale to ≤300px, encode JPEG - Add thumbnail_data BYTEA column to fruit_images and publication_fruit_images - New GET /api/v1/fruits/:id/images/:imageId/thumbnail endpoint (fallback to full data) - New GET /api/v1/publications/:id/fruit-images/:imgId/thumbnail endpoint - New POST /api/v1/admin/backfill-thumbnails to retroactively generate thumbnails - ListFruits response now includes synonyms and thumbnail_url per fruit - Replace FruitList table with responsive FruitCard grid (thumbnail + name + OSDB ID + type + synonyms) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

 - Users can view a "Hello, OSDB!" landing page that confirms the backend is reachable via the Vite proxy.
 - Users can create, view, edit, and delete fruit varieties, including managing synonyms and uploading images.
 - Administrators can bulk-import the legacy fruit database from XML using `scripts/import_fruits.py`, and then import all publications (cover images, linked fruits, PDFs, fruit images) using `scripts/import_publications.py`.
+- Users can search fruits by name or synonym (case-insensitive, debounced) and filter by type or combined-type alias (e.g. "Birnen- und Quittensorten") from the fruit list.
 - Users can manage publications (books, catalogues) with cover images, linked fruits, per-fruit PDF descriptions, and fruit images; fruit detail pages show publication descriptions and images.

juliaandClaude Sonnet 4.6	78c23557da	feat: fruit search by name/synonym and type filter (story #06 ) Backend: List repo query gains name (ILIKE with wildcard escaping on name + synonym LEFT JOIN, SELECT DISTINCT) and types (ANY cast) params; handler parses ?name= and ?type=, resolves combined-type aliases from domain.FruitTypeAliases, validates plain types against validFruitTypes to prevent Postgres enum cast errors. ORDER BY f.name, f.id for stable pagination. Frontend: listFruits gains optional {name, type} params; fruitStore adds searchName/searchType state and setSearch action (resets offset, refetches); FruitList.vue wires text input (debounced 300 ms + Enter) and flat type dropdown (17 enum values + 4 aliases per spec §5 order); debounce timer cleared on unmount.
