The real bug behind "Leona's Birthday, 5 days left" showing 0% filled:
Mode B (recurring span: previous -> next occurrence) only ran for
app-tracked events, while the upcoming-queue / picked-event paths still
anchored from first-seen (so a yearly birthday started at 0%).
- EventEntity now carries isRecurring/recurrenceLabel (populated from the
shared task data) so the auto-select and picker paths know the rule.
- resolveSpan() centralizes the window: recurring -> prev/next occurrence
everywhere; one-off -> explicit start / tracking date / first-seen.
- A yearly birthday 5 days away now reads ~98% (≈360/365 days elapsed).
