docs: add RD-36 — rename the stale ui/dashboard/ folder

RD-03 moved the dashboard page into the `overzicht` context and RD-04 left the
folder name alone, recording it as stale. It stays stale: the folder is named
after a page that lives somewhere else, so a reader looking for the dashboard
finds four sections that are not it.

Measured cost: 8 `git mv`s and four import lines in one file. Fold in two doc
paths that still name the moved page.

 The ID order already respects every dependency, so it is the recommended running order.
 
 **Independent tickets.** RD-15 through RD-19 depend only on RD-01. Pull them forward to fill
 a short session. Take RD-15 early: it makes every later repository search faster.
 
+**RD-36 is last by number, not by dependency.** It needs only RD-04, it is 8 `git mv`s plus
+four import lines, and it collides with nothing else in the table — RD-27's move is confined to

 **Two ordering traps the table encodes.** RD-01 must precede RD-30, because RD-01 copies its
 ticket template out of the directory that RD-30 archives. And four tickets edit the same two
 documents in different sections — RD-09 rewrites the submit-idiom teaching, while RD-31 and
