BrandSelector
- Now fully controlled — drops the internal `selected` state that could drift
from the prop source of truth
- Full-plan auto-select effect compares against the live selection and only
fires when out of sync, removing the infinite-loop risk if parents passed an
unstable onSelectionChange (now also ref-stashed)
- Search input appears when there are more than 12 brands; Turkish-locale
case-folding so "Volkswagen"/"volkswagen" both match
- No-match state for empty search results
TrialUrgencyBanner
- Three urgency tiers (soft 7d, urgent ≤3d, critical ≤1d) — colors and
tighter copy escalate as the trial winds down
- Adds an elapsed-time progress bar so "3 days left" reads as 90% used at a
glance (number alone undersells urgency at the tail)
- LS dismissal key now userId-scoped (mirrors subscription page)
- Banner emits `tier` alongside days for funnel segmentation
