Fix phone version titles for the active 2.x consumer cohort

VersionGraph's intrinsic max-content host defeats its existing title ellipsis on phones. Remove that width constraint while retaining original commit titles, IDs, ancestry, filters, virtual keyboard navigation and the readable type floor. The existing browser journeys now exercise 205 commits over 29 lanes and the already canonical Quiet day/hour label.
