fix: zoom-aware dropdown positioning in session list + archive/research menus

getBoundingClientRect() returns zoom-scaled coords, but
window.innerWidth is unscaled. rect.right/z computed offset was
wildly negative at ui-scale-125, pushing dropdowns off-screen left.
Both createSessionItem() dropdown (rename/delete/archive) and
_showDropdown() (archive/research library cards) affected.
