v0.2.7 — header wrap fix from upstream

Cherry-picks the upstream header-wrap fix (0aee45f) into the submodule. The 'Abfahrt in' / 'Departure In' header column now anchors its text to the column's right edge via absolute positioning, so long translations overflow leftward into adjacent empty space instead of wrapping to a second line.

Replaces the margin-right workaround from v0.2.6.

No other functional changes from v0.2.6.
