perf: Event-Cache von ±8 Wochen auf ±10 Monate erweitern

Damit lädt beim Swipen durch Monate erst nach ~10 Monaten in beide Richtungen erneut Daten nach. Vorher reichte der Cache nur ±2 Monate, sodass nach 2-3 Wischen ein Spinner kam. - CACHE_BUF 56 → 300 Tage (initial ±10 Monate) - PREFETCH_EXT 56 → 180 Tage (Verlängerung bei Edge ~6 Monate) - PREFETCH_EDGE 28 → 90 Tage (Trigger ~3 Monate vor Cache-Rand) Version v6 → v7.
