Implement AITBC wallet adapter for REST API wallet creation

- Added AITBC chain configuration to MultiChainWalletAdapter chain_configs
- Created AITBCWalletAdapter class with full wallet operations:
  - create_wallet: Generates AITBC Bech32 addresses
  - get_balance: Mock balance query (100.0 AITBC)
  - execute_transaction: Mock transaction execution
  - get_transaction_history: Mock transaction history
  - verify_address: Validates AITBC Bech32 address format
- Updated get_adapter method to handle ChainType.AITBC
- Added secrets import for key generation
- Wallet creation now works via REST API endpoint
