Fix employment history: sort present roles first so current employer fills slot 0

_fill_employment_history iterated work_history in YAML order. work_history[0]
was AMD (Feb 2022–Jan 2025), which was being written into the form's first
employment slot — overwriting the 'Inner Loop' that fill_form had already placed
via the current_company rule.

Sort by present/ongoing first before iterating so the form always gets the
active employer in position 0, regardless of how the user orders work_history
in profile.yaml.
