Add score card, 52W range bar, short interest, options tab, CSV exports

Overview:
- Score card: green/yellow/red signals for valuation, growth, profitability,
  leverage, momentum (vs 52W high), and short interest
- 52W high/low visual range bar with current price marker and % context
- Short interest metrics row: % of float, days to cover, shares short vs
  prior month
- Replaced static 52W High/Low metrics with volume and avg volume

Options tab (new):
- Expiry selector across all available expirations
- Put/call ratio by volume and open interest with bullish/bearish label
- IV smile chart (calls + puts) with ATM marker
- Open interest by strike (calls above, puts mirrored below axis)
- Full chain table (calls/puts) in expandable section

CSV exports:
- Download button on each financial statement (income, balance, cash flow)
- Download button on earnings history table

Also fix top padding cut-off: block-container padding-top 1rem → 3.5rem
