Problem Summary:
Adjust the indentation format of the `init_be` and `entry_point`
scripts, as well as the duration of loop execution.
Adjust the smallest unit of all indentations to a single tab character,
and modify the loop duration when checking the BE startup status,
changing both from 300 seconds to 30 seconds to speed up the overall
Docker startup time.
