fix: add proper autocomplete and name attributes to email update form

Adds name="email" to the email field and fixes the password field's
autocomplete from the invalid "password" to "current-password", also
adding name="current-password". This helps password managers correctly
identify the form as a settings change rather than a login form,
preventing them from autofilling the username into the email field.

Closes go-vikunja/vikunja#2512
