Ticker panel polish: freshness up top, radar pad, indicator grid,

verdict de-dup, target picker on take

Five fixes from prod review:

1. Data freshness row moves from the panel foot to directly under the
   header - data age is a first-look concern.
2. Radar fingerprint labels were clipped left ("Momentum") and right
   (value digits): label padding widened to fit "momentum 100" on both
   anchored sides.
3. Indicators tab: the one-at-a-time dropdown (which also clipped) is
   gone; all indicators load in parallel as quiet outlined cards - EMA
   cross with its colored signal, RSI/ADX with a one-line human read
   (overbought / trending / ...), values formatted to 2 decimals
   instead of 4, normalized score demoted to a corner note.
4. Recommendation verdict line de-duplicated: the backend reasoning
   already starts with the action label, so it now replaces the
   headline instead of repeating under it.
5. Mark-as-taken: the take form gains a target selector listing every
   detected target with price / probability / classification (primary
   preselected), and the card warns when the primary target sits below
   15% probability. Why the scanner promotes such a target to primary
   is a separate (backend) question.
