fix: prevent fight view scrolling on mobile with tab bar

All pages used h-[calc(100dvh-4rem)] which only subtracted the top
navbar but ignored the mobile tab bar's pb-14 bottom padding, causing
content to overflow and scroll. Changed all pages to h-full so they
fill the flex parent (main element) which already handles both the
navbar and tab bar spacing correctly.
