The bulk-delete modal previously used a password input as a confirmation gate, with an Enter-to-submit handler. Windows Hello / passkey flows that target password fields were able to autofill and synthesise an Enter keystroke, which submitted the form and triggered the destructive delete without an explicit click on the red Delete button (Rekoo's report in #417). Replace the password gate with a GitHub-style typed-literal pattern: the user types the literal "DELETE" (English, case-sensitive) into a plain text input. The Delete button stays disabled until the input matches, and there is no Enter-to-submit handler — only an explicit click on the red button proceeds. Plain text inputs aren't subject to password autofill or passkey ceremony so the auto-submit class of bug is gone. Server side, drop the bcrypt password verify on /admin/events/bulk-delete and the related INVALID_PASSWORD response. The server's auth boundary remains adminAuth + requirePermission('events.delete'); this matches DELETE /admin/events/:id which has never required a re-entered password. The client-side typed gate is the safeguard against accidental clicks. i18n: drop password-related keys, add confirmLabel + confirmHelp across en, de, nl, pt, ru. The literal "DELETE" stays English in all locales to keep the gesture immune to translation drift and unambiguous. Verified locally: typed-DELETE sanity spec covers the gate (wrong case disabled, correct enables, Enter-on-input no-ops, click submits, events deleted). Existing 03-bulk-archive smoke remains green.
