demo: profiler — scrolling ticker basket with live prices + click-to-filter

J asked: "kind of like a scrolling ticker that has all of the companies
and their stock prices and where they fit in the map." Implemented as
a horizontal-scroll strip at the top of /profiler:

  9 public issuers in this view · quotes via Stooq · 669ms
  ┌────┬────┬────┬────┬────┬────┬────┐
  │TGT │JPM │BALY│ACRE│FCBC│NREF│LSBK│ ← live price + day-change per
  │129 │311 │... │... │... │... │... │   ticker, color-banded by
  │+.17│+1.5│... │... │... │... │... │   attribution kind
  └────┴────┴────┴────┴────┴────┴────┘

Each card carries:
  - ticker + live price + day-change % (red/green)
  - attribution count + kind (exact / direct / parent / associated)
  - left bar color = strongest attribution kind (green for direct
    issuer, amber for parent, blue for co-permit associated, gradient
    when both direct and associated apply)
  - tooltip on hover lists the contractors attributed to this ticker
  - click toggles a filter on the table below — clicking TGT cuts the
    200-row list down to just TARGET CORPORATION + TORNOW, KYLE F
    (Target's primary co-permit contractor)

Server-side:
- entity.ts exports fetchStooqQuote (was internal)
- new POST /intelligence/ticker_quotes — accepts {tickers: [...]},
  fans out to Stooq.us in parallel, returns
  {ticker, price, price_date, open, high, low, day_change_pct,
   stooq_url} per symbol or null for non-US listings (HOC.DE, SKA-B.ST,
   LLC.AX). Capped at 50 symbols per call.

Front-end:
- mcp-server/profiler.html — new .basket-wrap section above the
  controls. buildBasket() runs after profiler_index loads:
    1. Aggregates unique tickers from .tickers.direct + .associated
       across all surfaced contractors
    2. Renders shells immediately (ticker symbol + "—" placeholder)
    3. Batch-fetches quotes via /intelligence/ticker_quotes
    4. Updates each card with price + day-change in place
  Click on a card sets a tickerFilter; render() skips rows whose
  attributions don't include that ticker. "clear filter" button on
  the basket strip resets it.

Verified end-to-end on devop.live/lakehouse/profiler:
  Default load → 9 issuers, live prices populated in 669ms
  TGT click   → table filters to TARGET CORPORATION + TORNOW, KYLE F
                (the contractor who runs 3 of Target's recent permits
                gets the TGT correlation indicator)
  JPM card    → $311.63, +1.55% — JPMorgan-adjacent contractors
  Tooltip     → list of contractors attributed to the ticker
