Improve AI import UX and recognition quality

- AJAX upload with progress bar — browser no longer blocks during upload;
  redirects to status page immediately after file transfer completes
- Improved Ollama prompt: clearly separates manufacturer (brand logo),
  product name (descriptive text) and number (article code) to fix
  misidentification like treating the product name as manufacturer

-Analyze this nail polish bottle image carefully.
-Extract the following data and respond ONLY with valid JSON, no other text:
+You are analyzing a nail polish or nail product bottle/container image.
+Extract exactly these three fields and respond ONLY with a valid JSON object, no explanation, no markdown:
 {
-  "name": "the nail polish color name",
-  "number": "the product number or color code (often printed on bottle or cap)",
-  "manufacturer": "the brand name printed on the bottle"
+  "name": "the full product name or color description (e.g. 'Modeling Base Calcium Neutral Pink', 'Ruby Red', 'French White')",
+  "number": "the product code or article number printed on the label or cap (digits, letters, hyphens only — e.g. '12392-7', '123', 'NP-05')",
+  "manufacturer": "the brand or company name (the logo/brand printed on the product — e.g. 'NEONAIL', 'OPI', 'essie', 'Catrice')"
 }
-If a value is not visible or unclear, use null.
+Rules:
+- manufacturer = the brand/logo name (usually prominent on the label)
+- name = the descriptive product/color name (NOT the brand)
+- number = numeric or alphanumeric code (NOT the color name)
+- If a value is genuinely not visible, use null
