fix: relax password requirements and improve password UI

- Reduce minimum password length from 12 to 8 characters
- Make special characters optional for gallery passwords
- Lower strength requirement from score 3 to 1 for galleries
- Add eye icon toggle for password visibility on each field
- Remove redundant 'Show passwords' checkbox
- Add translation for password security requirements error
- Update both English and German translations

This allows users to use simpler passwords like 'Sommer2025\!' for events
while maintaining security through other measures like expiration dates.
