fix(manage): full-width form below description, sign-out into handle row, centered actions
- Move every field below name/description out of the avatar+fields
right column into a new full-width .profile-form-stack so chip
groups, Atmosphere services, and link editors get the whole card
on desktop.
- Drop the duplicate "Signed in as @handle / Sign out" lockup above
the card; the handle row inside the form now anchors a sign-out
pill on the right (button uses formAction="/oauth/logout" +
formNoValidate so it doesn't trip the parent profile form).
- Center the Update / View / Remove action row inside the card.
- Convert Custom links + Developer icon sections from
fieldset/legend to div/span so the .profile-form-field flex gap
finally applies between the label and its content (legend doesn't
participate in flex layout). Drop the now-redundant
.custom-link-list margin-top + custom-link-add margin-top.
