When attempting to set an AP name with less than 5 characters, it unexpectedly adds extra characters to the provided name.

Steps to Reproduce:

1. Attempt to set an AP name with fewer than 5 characters, e.g., "ABC" or "HI"
2. See inside the Serial that the resulting AP name has the extra characters. "ABCTAL", "HIRTAL".

Expected Behavior:
When setting an AP name with less than 5 characters, it should retain the provided name as is, without adding any extra characters. So, "HEY" should remain "HEY".

Actual Behavior:
Additional characters are added to the AP names with fewer than 5 characters, resulting in unexpected names. For instance, if "HEY" is set as the AP name, it becomes "HEYTAL," and if i set "A" is set, it becomes "AORTAL."

When I changed the code within evil_portal_storage.c to use an empty string for the AP name app->ap_name = (uint8_t *)""; the name becomes "PORTAL," indicating that the characters are being layered on top of the "PORTAL" string.
