Trial users previously got no reminder of remaining days until the urgent
(<=7d) amber banner appeared, leaving most of the 30-day window with no
conversion nudge. Added a calm, brand-toned TrialProgressBanner shown when
more than 7 days remain: days left, a progress bar (elapsed share of the
30-day trial), and a "Planını seç" CTA that scrolls to checkout and fires
trial_progress_cta_clicked. The urgent banner still owns the final 7 days.
