refactor: convert spanish-verb 6-way cl-case to alist dispatch

org-drill-present-spanish-verb had a 6-branch cl-case where each
branch differed only in two values: which subheading to reveal
(Infinitive or English) and which prompt string to show.  Inlined
into a 50-line block of nearly-identical setq calls.

Extracted the (reveal . prompt) pairs into a defconst alist and
reduced the dispatcher to a random-pick + apply-pair pattern.
Function drops from 51 lines to 14.  Existing branch tests still
pass — they mock cl-random to a specific index, and the alist's
order matches the previous case order.
