Scanner: expand default watchlist from 15 to 37 sector-diversified names

Browse Source 
The previous default leaned heavily on mega-cap tech. EDGE setups
are rarer than that — you want a wider net across sectors to catch
the 1-3 setups per week that actually qualify. Curated to 37 names
that are all optionable mid+ cap with reasonable LEAPS liquidity:

  Indices/ETFs: SPY, QQQ, IWM, DIA, SMH, XLF, XLE, XLK
  Mega-cap tech: AAPL, MSFT, NVDA, GOOGL, META, AMZN
  Semis: AMD, INTC, TSM, AVGO, MU
  High-vol/event-driven: TSLA, NFLX, COIN, PLTR, SHOP, UBER, MARA
  Financials: JPM, BAC, GS, V
  Healthcare: LLY, JNJ, UNH
  Consumer/energy: XOM, WMT, DIS, MCD

Also bumped the per-scan cap from 30 to 100 so users can paste
custom lists up to 100 symbols (the previous 30-cap silently
truncated lists like the new 37-name default).

Full default scan completes in ~3.5s with zero errors and correctly
surfaces only the genuine EDGE setups (live test: NVDA / INTC / AAPL
flag, the other 34 do not).
