Configuration for Default Email and Phone in Customer Feed

[Shinde-nutan]

The generate#CustomerSyncFeed service creates a CSV file to sync customer with NetSuite.
Some customer records may lack critical details, such as email or phone numbers, which are required by clients for a valid feed.

Problem:

Currently, the service does not handle cases where customer email or phone details are missing. There is no existing mechanism to configure default values for these fields.

Expected Behavior:

• Introduce a configuration option to define default values for email and phone.
  • Example: Default email ([email protected]) or default phone (+0000000000).
• If a customer record lacks email or phone details:
  • Populate the missing fields using the configured default values.
• Ensure the configuration is flexible to allow client-specific default values.
