Subject: [PATCH] fix(ui): match hyphens and dots in mentions

matchedUsers builds the mention_username_list sent with a new comment,
but its pattern stops at "-" and ".", while parseUserInfo, which turns
the same text into links, accepts both. A comment mentioning the user
"jane-doe" links to /users/jane-doe, but the mention notification is
looked up for "jane": another user receives it, or nobody does.

Use the parseUserInfo pattern in matchedUsers so the users who are
notified are the users the comment links to.
