tray tooltips: tilt persists while portal is open; PRV|NXT pinned to corners — TDD

- TrayTooltip adds .tt-active to the .tray-role-card / .tray-sig-card cell while its tooltip is open & removes it on _hide. The hover-tilt selectors gain .tt-active alongside :hover, :focus so the card stays tilted while the user is hovering the portal itself rather than the cell.
- #id_tooltip_portal: .fyi-prev / .fyi-next pinned to the bottom corners w. 1rem outside the panel (bottom: -1rem; left/right: -1rem) — same anchor the @stat-block-shared mixin uses for fan / sig / sea, restated here since the portal isn't covered by that mixin.
- 2 new TrayTooltipSpec specs (.tt-active added on hover, removed on _hide; for both role & sig branches).
