fix(ios): respect safe-area insets so chrome clears the notch/home bar

Content was drawing under the iOS status bar and home indicator because
the app uses viewport-fit=cover + black-translucent but the fixed/sticky
chrome didn't reserve the safe areas.

- bottom nav (MyLayout): move the 50px row into an inner box and let the
  bar extend by env(safe-area-inset-bottom) so icons sit above the home
  indicator (previously the fixed height clipped the inset padding).
- top headers gain env(safe-area-inset-top): HomePageTopBar, ExploreTopBar,
  SearchTopBar, CartHeader, ChatHeader, and wrapper-padded HeaderWithSupport
  / ProfilePagesHeader (so their absolutely-positioned buttons shift too).
- chat input pads bottom by the inset; chat scroll area height accounts for
  the taller header/input.
- _index.tsx no longer overrides the viewport meta (it was dropping
  viewport-fit=cover on the home page); the global one in root.tsx wins.

env(safe-area-inset-*) is 0 on non-notch devices, so desktop/Android render
identically — only iOS gains the padding.
