fix: prevent HTML encoding of forward slash in booking confirmation (#26949)

- Add interpolation: { escapeValue: false } to AttendeeRequestEmail.tsx
- Add interpolation: { escapeValue: false } to attendee-request-email.ts
- Add interpolation: { escapeValue: false } to bookings-single-view.tsx

This prevents special characters like '/' from being HTML-encoded to '/'
in booking confirmation emails and success page dialogs.

Fixes #26938
