feat: Add per-symbol trading controls for SOL and ETH

- Add SymbolSettings interface with enabled/positionSize/leverage fields
- Implement per-symbol ENV variables (SOLANA_*, ETHEREUM_*)
- Add SOL and ETH sections to settings UI with enable/disable toggles
- Add symbol-specific test buttons (SOL LONG/SHORT, ETH LONG/SHORT)
- Update execute and test endpoints to check symbol enabled status
- Add real-time risk/reward calculator per symbol
- Rename 'Position Sizing' to 'Global Fallback' for clarity
- Fix position manager P&L calculation for externally closed positions
- Fix zero P&L bug affecting 12 historical trades
- Add SQL scripts for recalculating historical P&L data
- Move archive TypeScript files to .archive to fix build

Defaults:
- SOL: 10 base × 10x leverage = 100 notional (profit trading)
- ETH:  base × 1x leverage =  notional (data collection)
- Global: 10 × 10x for BTC and other symbols

Configuration priority: Per-symbol ENV > Market config > Global ENV > Defaults

+-- Fix Zero P&L Trades (CORRECTED VERSION)
+-- This script recalculates P&L for trades that were incorrectly recorded as $0.00
+-- IMPORTANT: positionSizeUSD already includes leverage, so we must divide by leverage
+-- to get the actual capital at risk, then multiply by price change %

+-- CORRECT P&L Formula:
+-- 1. actualCapital = positionSizeUSD / leverage (remove leverage to get base capital)
+-- 2. priceChange% = (exitPrice - entryPrice) / entryPrice * 100
+-- 3. accountReturn% = priceChange% * leverage (leverage amplifies returns)
+-- 4. realizedPnL = actualCapital * (accountReturn% / 100)
+--
+-- Simplified: realizedPnL = (positionSizeUSD / leverage) * (priceChange% * leverage) / 100
+--                          = positionSizeUSD * priceChange% / 100
