This update removes redundant overrides for start dates in the UK and New Zealand reporting modules. Previously, users couldn't easily set the start date themselves, rendering the field on the form view ineffective. This change simplifies the reporting process and aligns with the new user interface functionality.

These overrides are useless now that the user can access the return type form view and configure himself the start_date.

Overriding _get_start_date_elements should be avoided as much as possible as this is making the field on the form view useless if set.
