Adds a Spanish (Latin American, formal "usted") translation, as discussed in biolab/orange3#7352.

Changes

• i18n/es/msgs.jaml: collected with trubar collect against current master. Entries marked false in si/msgs.jaml are also false here; there are no null entries.
• i18n/trubar-config.yaml: registers es (Español / Spanish).

Spanish needs no plural helper like plsi: plural forms use the default pl() with singular|plural where needed.

Checks

• The CI check, run for es (trubar collect + merge + missing), reports no missing or obsolete messages.
• trubar translate builds without errors, and the translated sources compile.
• An automated check of every string: placeholders, HTML, accelerators (&), line breaks, and f-strings that compile with the same variables. No issues.
• The same translation (built for 3.40.0) was installed and used with all widgets.

The companion PRs for the other two repositories are linked from biolab/orange3#7352.
