Fixes #1220.

What changed

This updates the event and organizer danger-zone delete confirmations so the typed confirmation is compared against the same localized delete translation used by the input placeholder.

That means translated confirmation words such as German löschen can enable the delete button instead of requiring the English literal delete.

Validation

• npm run build:csr passes
• Targeted ESLint on the changed files reports no errors; existing warnings remain in those files
• Full npm run lint currently fails on existing repository-wide lint errors unrelated to this patch
• npm run build-strict:csr currently fails on existing repository-wide TypeScript errors unrelated to this patch

Notes

The same hardcoded confirmation pattern existed in both event deletion and organizer deletion, so both were updated for consistency.
