refactor(strategies): move JSON freezate sotto strategy_crypto + patch runner

- git mv strategies/{btc,eth}_*.json → src/strategy_crypto/strategy_crypto/strategies/
- Cancellata directory root strategies/ (ora package data del member strategy_crypto)
- I JSON sono inclusi nella wheel via force-include nel pyproject del member
- scripts/run_paper_trading.py:
  * Import paper_trading.* → strategy_crypto.backend
  * Default --strategies-dir letto da importlib.resources.files('strategy_crypto') / 'strategies'
  * PaperRepository(settings.strategy_crypto_db_path) + init_schema()
  * Rimosso Repository(settings.db_path).init_schema() (GA init non e' responsabilita' del paper)
- Verifica: importlib.resources trova i 2 JSON nel package
