fix (forms): change api for "Tell Post Office someone died" form

[sajclarke]

Description

This PR updates the post-office redirection form for deceased individuals. It includes schema updates to match the Figma design and improves email error handling by gracefully failing if unable to connect to the SMTP server.

Type of Change

• Bug fix
• New feature
• Breaking change
• Documentation update

Changes Made

• Update post-office redirection deceased form schema to match Figma design specifications
• Add middle name field to deceased person's information
• Change "applicant" section name to "deceased" for clarity
• Rename "dateOfBirth" to "dateOfDeath" in the deceased section
• Remove email and telephone fields from deceased person section
• Remove ID number and passport number fields from deceased section
• Update label capitalization (e.g., "Address Line 1" → "Address line 1")
• Rename "postalCode" to "postcode" for consistency
• Improve email service error handling to silently fail if SMTP connection is unavailable instead of throwing errors
• Update email template for post-office redirection notice

Notes

The schema changes align the form structure with the Figma design, removing contact information from the deceased person section and simplifying the form while adding the middle name field. The email service changes ensure the application continues gracefully if email cannot be sent due to SMTP server connectivity issues, rather than throwing an error.

Testing

• Form validation tested with new schema structure
• Verify deceased person fields display correctly
• Test email template renders properly with template updates
• Verify form submission succeeds even if email fails to send
• Test all conditional fields work as expected
• Validate required/optional field constraints
• Check responsive design on all device sizes
