Adds Authorization Response Validation subsection with the metadata-keyed decision table, updates the flow diagram, lists RFC 9207 under Standards Compliance, and adds a Mix-Up Attacks entry under Security Considerations.

The @-handle regex was matching inside email addresses (e.g., @microsoft in <[email protected]>), and angle-bracket emails then broke MDX parsing. Now converts <email> to (email) and only links @handle when not part of an email.
render-seps.ts auto-links @-handles in author lines to GitHub. With an email present it matches the domain (e.g., @microsoft in <[email protected]>), and the surrounding angle brackets then break MDX parsing in the generated docs/seps page (mint sees `<user[` as a malformed JSX tag). The previous commit fixed the regex; this commit reverts that and instead drops the email so the existing simple regex works. SEP-1034 has the same latent issue ([email protected] links to github.com/gmail) but is non-blocking and out of scope here.
