The login page has its own inline <style> and doesn't load static/style.css,
so it never inherited the main app's touch-device rule that pins text inputs
to 16px. Its fields are 0.95rem (~15.2px) and the dynamically-inserted 2FA
input is 14px, so iOS Safari zooms the whole page when either is focused -
on the very first screen every user sees.
Add a `@media (hover: none) and (pointer: coarse)` rule raising
`input:not(.remember-check)` to 16px, mirroring the main app's approach.
!important also lifts the 2FA input, which pins font-size:14px inline.
Desktop is unchanged (inputs stay 0.95rem).
