[improvement] Generate config report considering newly added configurations

[24seconds]

Description

Recently work_time_default_value and break_time_default_value configurations are added. Therefore, the config report should reflect it.

• If the work_time_default_value is not given, then 'ok' would be x and the reason would be not specified
• If the work_time_default_value is given, then 'ok' would be o and the reason would be empty
• this rule works same as for break_time_default_value
