new: add password visibility toggle on all password fields

Reusable ``password_toggle.blade.php`` partial that wraps every
``input[type=password]`` with an eye icon button. Clicking it
toggles between hidden and visible text. Handles Bootstrap modals
via ``shown.bs.modal`` event. Applied on login, register, password
change (shop + admin), password reset, and first login pages.
