design: no Notifications box on Account and Server > Settings

Event notifications are not built (panel-notifications is a roadmap
candidate), and the outline of both screens forced a box that could only
say so. The owner's decision (2026-10-10): take the boxes out of the
mockups; they are drawn again as the first step of that feature's plan.

  - src/account.html: box 03 Notifications removed, DMARC reports is 03;
    the lead and the e-mail help no longer promise notifications or a
    reset link.
  - src/settings.html: box 02 Notifications removed, Sending rate limits
    is 02; the lead no longer lists notifications.
  - outlines.json regenerated (check.py --write): the two boxes are gone
    from account and settings, nothing else moved. 0 violations.
