Ticker page: one unified drill-down panel, no card salad

The previous pass kept a stack of independent glass cards (header,
recommendation, chart section, tab pills, per-tab sections), which read
as clutter. Now the page is a single casting, like the mockup:

One glass panel containing:
- header (identity, price, chips | actions + score fingerprint)
- inline hairline tab row (Analysis / Indicators / S/R Levels /
  Sentiment / Fundamentals) with the chart-overlay pills riding on the
  right of the row during Analysis
- tab body: Analysis = the candlestick chart; other tabs render their
  panel inside via .hz-frameless, which strips the nested card chrome
  (no card-in-card)
- panel foot: data freshness row (frameless now) with per-source
  refresh

Below the panel, only on Analysis: the recommendation module and a
two-column Standing | Dimensions grid. Nothing removed; the standalone
Tabs bar, the separate chart card, and the duplicated section stack are
gone.
