### Processing Flow Description

The method processes in the following major phases:

1. **Bean Initialization Phase (lines 1046-1060)**: Initializes all form beans - common info, web new info, eo net, eo TV, eo tel, contract service, mansion info, and payment method info.

2. **Campaign Check Phase (lines 1062-1078)**: Checks campaign eligibility. If campaign check fails, sets result code "1" and redirects to screen FUW00166.

3. **New Customer Verification Phase (lines 1080-1089)**: For new applications (MSKM_KBN_NEW), verifies customer info. If invalid, throws JCCBusinessException with error code 0013 (Contract Status Error).

4. **Data Preparation Phase (lines 1091-1115)**: Sets mail form bean, mineo set plan info, and DNSKH DOI flags across all service beans. Saves the add_input_map to session.

5. **Wiring Service Type Phase (lines 1117-1172)**: Determines the applied wiring service type (home/mansion). If PLC relay or mesh WiFi is selected, calls callSvcFUSV0376 to get device model codes.

6. **Mapper Initialization and Registration Phase (lines 1174-1496)**: Generates the paramMap and initializes mappers. For non-bulk registrations, invokes the extensive set of mapper methods that register all service contracts.

7. **invokeService Phase (lines 1525-1640)**: Calls the core service. On JCCWebServiceException, routes to extensive error handling based on templateId and itemId.

8. **Post-Commit Phase (lines 1642-1685)**: Executes AxM linkage service, checks business regulations, handles bulk registration data retrieval, sets next screen to FUW00122, and sends completion mail.
