fix(prof): fixed asserting length of INI

[realFlowControl]

Description

When converting the environment name to an INI name we asserted on the wrong length, using the ZAI_CONFIG_ENTRIES_COUNT_MAX (300) instead of the ZAI_CONFIG_NAME_BUFSIZ (60). So in theory we could have used ENV names for config options that result in INI names longer then the fixed 60 bytes buffer.

Reviewer checklist

• Test coverage seems ok.
• Appropriate labels assigned.

Test failures look unrelated. Code change looks correct.
