fix: tab layout, clear search state, and cleanup

UI: remove trackertable from the Search tab and reorder widgets to correct layout. Tab helper: add QLayout directly instead of wrapping it in a temporary QWidget to avoid extra nesting. Search helper: clear the trackertable rows and reset state.posts when starting a new search to ensure fresh results. Minor: import check_space in main and simplify an unused loop variable in libtorrent_int for clarity/linting.
