Issue Summary

When viewing a ticket in Jira Service Management Cloud, the date format in date picker fields differs between the agent view and the customer portal. The agent view correctly respects the user's language preference (e.g., yyyy年mm月dd日 for Japanese), but date picker fields in the customer portal display dates with a 2-digit year format (e.g., dd/mm/yy) regardless of language settings. There is no configuration option available to users to control or change the date format in the portal.

Steps to Reproduce

1. Configure a JSM Cloud instance with Japanese language preference
2. View a ticket with a date picker field in the agent view — the date displays as yyyy年mm月dd日
3. Access the same ticket from the customer portal
4. Observe the date picker field in the portal view

Expected Results

The date picker field in the customer portal should display dates respecting the user's language preference settings (e.g., yyyy年mm月dd日 for Japanese, with a 4-digit year).

Actual Results

The date picker field in the customer portal displays dates in dd/mm/yy format with a 2-digit year, regardless of the configured language preference.
