localization: ship es-ES

Complete Spanish catalog across all three namespaces, 1129 keys,
machine-translated then reviewed for terminology and plurals.

Fixed on review: an awkward literal fragment in settings.accounts.description
("Quién tiene acceso, y como qué") reworded to use the established
role → "función" glossary term instead of an ad-hoc phrase. Everything
else held up — "compositor" for the chat composer avoided the same
Editor-collision German needed fixing for, Minesweeper stayed
untranslated matching pt-PT/fr-FR/de-DE precedent, and the impersonal
"se" constructions used for the file-operation plurals (Se copió /
Se copiaron) read correctly at both n=1 and n=0 — Spanish's plural
rule is one/other like English, count=0 takes the plural branch.

All 17 plural entries verified at count 0/1/2.

This closes out the three-locale rollout: es-ES, de-DE and fr-FR all
now in SHIPPED_LOCALES and all three parity tests, each shipped in
its own commit only after passing review. pt-BR stays out per the
owner's call — European Portuguese first, Brazilian is a separate
decision.
