fix(feed): don't tell people to click an indicator that isn't a button

The saved pip borrowed the bookmark button's label, so it read "Saved —
click to remove" on a plain span: hover, be told to click, click, nothing.
It gets its own "Saved" string. The status markers drop their sr-only
twin too — with a title already carrying the meaning, a screen reader
that surfaces title text said it twice.
