Refine fanout timeline (#12507)
* chore(endpoints/hybrid-timeline): don't pack inside getFromDb * chore(endpoints/hybrid-timeline): Redisから取得する部分のうちSTLに依存しなそうなところを別のServiceに切り出し * chore(endpoints/local-timeline): FanoutTimelineEndpointServiceで再実装 * chore(endpoints/channels/timeline): FanoutTimelineEndpointServiceで再実装 * chore(endpoints/timeline): FanoutTimelineEndpointServiceで再実装 * chore(endpoints/user-list-timeline): FanoutTimelineEndpointServiceで再実装 * chore(endpoints/users/notes): FanoutTimelineEndpointServiceで再実装 * chore: add useDbFallback to FanoutTimelineEndpointService.timeline and always true for channel / user note list * style: fix lint error * chore: split logic to multiple functions * chore: implement redis fallback * chore: 成功率を上げる * fix: db fallback not working * feat: allowPartial * chore(frontend): set allowPartial * chore(backend): remove fallbackIfEmpty HTL will never be purged so it's no longer required * fix: missing allowPartial in channel timeline * fix: type of timelineConfig in hybrid-timeline --------- Co-authored-by: syuilo <Syuilotan@yahoo.co.jp>
