Add project_id config and delegation methods to Python SDK

  - Add `project_id` param to CdpClient (reads from CDP_PROJECT_ID env var)
    and thread it through to EndUserClient and EndUserAccount
  - Add lazy-loaded EmbeddedWalletsCoreFunctionalityApi to ApiClients
  - Add 14 delegation methods to EndUserClient:
    revoke_delegation_for_end_user, create_evm_eip7702_delegation,
    sign_evm_{hash,message,transaction,typed_data},
    send_evm_{transaction,asset}, send_user_operation,
    sign_solana_{hash,message,transaction}, send_solana_{transaction,asset}
  - Add matching convenience methods to EndUserAccount with auto-resolution
    of first account address when no explicit address is provided
  - Add SendEvmAssetResult dataclass; export SendEvmAssetResult and
    EvmUserOperation from cdp.__init__
  - Fix pre-existing broken imports in solana_client, solana_account,
    actions/solana/sign_{message,transaction}, and test files caused by
    OpenAPI regen renaming *200_response to *_with_end_user_account200_response
