mobile: wrap tabs, trim portfolio + markets bar columns

Three pieces of phone-side feedback:

1. Indicator group tabs wrap onto multiple rows instead of
   horizontal-scrolling — every group is visible at a glance. Each
   button keeps its own bottom border so wrapped rows stay
   visually delimited; the container's bottom border is removed.

2. Portfolio holdings table hides Qty and Avg columns on mobile via
   the mobile-hide class (same mechanism as the indicator table).
   Remaining columns are the actionable ones: Ticker, Name, Last,
   P/L, %.

3. Markets bar at the bottom compacts to one row per chip —
   dot + code + change% only. The state word ("open" / "closed")
   is implied by the dot colour; the index label, price, and
   until-time are dropped on mobile. Grid columns drop their 220px
   floor so the full set fits the viewport without horizontal
   scroll (previously the bar scrolled within itself).
