- Approve endpoint now only creates Jira tickets immediately when
start_date is now/past; a new periodic job (every 15 min) catches
campaigns whose scheduled start_date has since arrived.
- Recurring campaign clones now go to pending_approval instead of
active, routing through the same manager-approval gate as any other
campaign; managers are notified instead of red_tech.
- Fix UTC conversion for the campaign approval start_date input and
extract shared isoToDatetimeLocal/datetimeLocalToIso helpers.
Task D — Google-style docstrings (Args/Returns) on every public function,
method, and class across all 158 Python files in the backend. Zero ruff D
violations (pydocstyle Google convention).
Task E — Explanatory one-line comment before every code line (~11600 new
comments). ruff check passes clean after isort re-sort.
