fix(enrollment): guide learners who submit the wrong template out of the trap (#240)

A learner clicked the enrollment link but submitted the Start Here roadmap
template (issue #237): the [ENROLL] title from the URL survived, the body
had the readiness checklist but no Full Name or Email Address fields, and
the needs-info bot told them to 'edit this issue and add the missing
information' without saying how. They also got the Gandalf first-issue
greeting mid-signup, which read as noise.

- registration.yml: the needs-info comment now explains the wrong-template
  cause, gives a copy-paste markdown block for the missing fields, spells
  out how to edit an issue body, and links the real enrollment form.
- learning-room-pr-bot.yml: the first-issue greeting skips [ENROLL] and
  [REGISTER] intake issues.
- start-here-roadmap.yml (main repo chooser only; learning-room copy
  unchanged): renamed to 'Course Roadmap Check-In (already enrolled
  students)' with an explicit not-an-enrollment warning and a link to the
  enrollment form.
