design: remove the 1.x panel-ui mockups and the redesign's stage-1 directions

docs/assets/panel-ui (the 1.x experiment, superseded by the redesign) and
docs/assets/panel-redesign/{a,b,c} (the three stage-1 directions; C was
taken) are history - the plan says so - and nothing builds, checks or
links them but the page that compared the directions. That page,
docs/assets/panel-redesign/index.html, which the documents link as the
way into the mockups, is now that: the screen map and what the design
holds, with a line saying where the removed folders are (git history).
build.py and check.py: 32 screens, 0 violations.
