Note

Low Risk
Only changes GitHub review ownership rules by reordering/clarifying CODEOWNERS; no runtime code paths are affected, but it can alter who must approve PRs.

Overview
Reworks .github/CODEOWNERS to make rule precedence explicit and correct by moving the global * fallback to the top, grouping product directories under @torusresearch/Web3Auth-Product, and placing the .github/CODEOWNERS rule last so it wins as the most restrictive match.

Also cleans up formatting/comments (including a minor wording change) to clarify that last match wins.
