feat(web): migrate AI tool settings to ProgressCard

Replace AIProgressBar and inline progress indicators with the new
ProgressCard component across all 5 AI tool settings. The three
useToolProcessor-based tools (remove-bg, blur-faces, upscale) now
destructure `progress` from the hook. The two custom-fetch tools
(erase-object, ocr) gain inline XHR upload tracking + SSE processing
progress with elapsed timer.
