Removed FOCUS-59040 - Fields: New Optional Custom Field Alias Updates

Enhances Custom Fields by adding a confirmation step when changing the alias of a newly created custom field that still uses its default database column name.

When editing the alias for these fields, users are prompted to choose whether to update only the display alias or to also rename the underlying database column. Selecting the new Also change the column name option updates both the alias and the physical database column, helping districts maintain meaningful field names while preserving the existing option to change only the alias when desired.
