fix: password encryption field styling to match nsec/seed login field

The password entry field on the encryption login screen was missing the
chat-input-container wrapper, causing it to look unstyled. Added the
same HTML structure as the nsec/seed field with CSS overrides to prevent
the header from hiding behind the input (position: relative instead of
absolute, zero auto margins).
