Two error messages on /admin/stations rendered Italian translations
that contain an apostrophe inside a single-quoted JS literal:
alert(result.detail || '{{ _("Errore nell\'eliminazione") }}');
Jinja outputs the apostrophe verbatim, so the JS string closed
prematurely:
alert(result.detail || 'Errore nell'eliminazione');
That syntax error blew up the entire <script> block, which means
stationManagement() was never defined and EVERY Alpine binding on the
page failed silently. Symptom: clicking "Nuova Stazione" did nothing,
DevTools showed "Alpine Expression Error: openCreateModal is not
defined".
Fix: swap outer JS quotes to double quotes and reword the IT string so
the apostrophe disappears anyway ("Errore nella eliminazione",
"Errore nella assegnazione"). Same for the assignment-error path.
Regression guard: src/frontend/flask_app/tests/test_template_js_syntax.py
renders /admin/stations and /admin/users with the IT locale forced,
extracts every inline <script>, and runs `node --check` on each. The
test is skipped if `node` is not on PATH so CI without Node still
passes. Verified the test catches the original bug (revert + run +
fail) before re-applying the fix.
