feat(absence): align passenger absence with per-day trip logic

Extend PassengerAbsenceEvent to include dailyTrips (list of { date, trip: Outbound|Return }) alongside existing concernedTrip.

In this absence service, when sending the Kafka event:

• If dailyTrips is non‑empty → use it as source of truth and derive concernedTrip as the union of all trips in dailyTrips.
• If dailyTrips is empty/null → fall back to the old full‑period behavior based only on concernedTrip.

The circuit service consumer now:

• Applies absences per day and per sens when dailyTrips is present (only those dates/trips are affected).
• Keeps previous full‑period behavior when dailyTrips is absent.
