fix: align heaven page top-bar right-side icons with other pages

The shared shell hides .app-header .overview-strip (the market tape) for
heavenView, which is intentional (the heaven page has its own dark header).
But hiding the tape removes the flex-grow element that normally pushes
.header-actions to the right edge, so on the heaven page the top-bar icon
group was left-shifted by hundreds of pixels (rightGap 792px at 1920 vs 20px
on reference pages).

Give the heaven .header-actions margin-left:auto in the shared shell so the
icon group stays flush right when the tape is gone, matching every other
page. The heaven page body, business logic, data, API and frozen content are
untouched.

Also bump the shell stylesheet cache version.
