Fix bridge request creation and clean up debug statements

- Bridge request creation now works with both 0x and ait1 addresses
- ait1 addresses must be at least 39 characters (Bech32 format)
- AITBCWalletAdapter correctly selected for chain IDs 1000/1001
- Removed debug print statements from create_bridge_request, validate_address, factory, and bridge initialization
- Bridge ID auto-generated by database (no manual assignment)
