Autofill instrument details from photos

When adding a new instrument, let users either take or upload photos of the brand logo and serial number (for example, front and back of a guitar headstock) and use image/OCR analysis to detect the Brand, Model, and Serial Number, then auto-fill the instrument details. Also support manual entry of brand and serial number that still triggers the same manufacturer lookup and autofill so users can choose between image analysis automation, manual entry with manufacturer autofill, or full manual entry.
