fix: write UTF-8 characters in apm.yml instead of escaped \xNN sequences

[alopezsanchez]

Description

PyYAML defaults to allow_unicode=False, which escapes non-ASCII characters (e.g. "López" → "L\xF3pez") regardless of file encoding. Add allow_unicode=True to all yaml.dump/safe_dump calls that write apm.yml files.

Fixes #387 387

Type of change

• Bug fix
• New feature
