Fixes English-page inconsistencies. The branch is rebased onto current main (d36ea09, including the merged Korean pages PR). No Korean page content, CI files, or workflow files were changed.

1. Homepage: renamed "Paddleway" to "Padsway" and removed the Pairy "In development" tag because Pairy is live on the App Store.
2. Product names: unified titles, headings, body, JSON-LD, llms.txt, about, and the products index. Corrected PadswayCore SDK, Send Approval Gate MCP, OMR Auto-Grader, QR Answer-Sheet Cropper, Exam + OMR Sheet Builder, Offline Classroom Tools, Scan-to-Grade, and Pairy. Also normalized the Korean-section llms.txt label for Scan-to-Grade.
3. Pairy: removed the In development tag from the homepage block and aligned the Pairy page title and heading with "Pairy: Connecting Devices".
4. Payments: product pages now say "Polar is the main checkout. Paddle is the alternative, for card or PayPal." Updated /pay/, privacy, terms, refunds, and llms.txt to match.
5. OMR comparison: added an OpenMCR row with GPL-3.0, matching the FAQ mention.
6. Scan-to-Grade: the Scan-to-Grade page makes no circled-word claim, and the OMR Auto-Grader page does state circled-word grading. No claim was removed or added.
7. About: the $1M revenue figure has repo sources in llms.txt and the product tier notes, so the format was unified from US$1M to $1M. No other unsourced numeric figures were present.
8. ShapeFit: replaced "Apple Notes" and "GoodNotes" with "note-taking apps" in the body, FAQ, JSON-LD, and site-data.
9. QR Cropper: merged the two QR-cropping FAQ entries into one in both HTML and FAQPage JSON-LD.

Skipped: pairy/mac still references the live /paddleway-support/ path. /padsway-support/ returns 404, so changing the URL would break a working link. Item 1 was scoped to the homepage.

Verification: every JSON-LD block parses with python3 json, FAQ HTML and JSON-LD match, product names match across title/h1/breadcrumb/JSON-LD/llms.txt, all hreflang links are unchanged from main, no /ko/ page content changed, and _products/gen/check_llms.py passes.
