fix: address third review round

- toggl_search_time_entries: when `period` is given alongside only
  one of start_date/end_date, fill the missing boundary from the
  period instead of silently ignoring the period and failing
  validation a few lines later (Copilot).
- utils.createReportEntry: drop a stray double blank line left over
  from the effectiveDurationSeconds extraction (Copilot).
