Adds the cursor-blink class to "no X" / "select a Y" placeholders across
core (calendar popup, board preview, search preview, detail split, notifs)
and plugins (chat, email, gitea, slideshow). Visual consistency with the
rest of the pixel-font UI.

Cursor blink, card-bar-pulse, sync spinner and the chat unread blink all
have deliberate cadences — letting body.anim-fast/anim-slow speed them up
turns them into unreadable strobes (or the sync icon spinning at 100ms).
Higher-specificity rules pin each one to its natural duration via
!important.
