feat(mobile): sqlite timeline (#19197)

* wip: timeline * more segment extensions * added scrubber * refactor: timeline state * more refactors * fix scrubber segments * added remote thumb & thumbhash provider * feat: merged view * scrub / merged asset fixes * rename stuff & add tile indicators * fix local album timeline query * ignore hidden assets during sync * ignore recovered assets during sync * old scrubber * add video indicator * handle groupBy * handle partner inTimeline * show duration * reduce widget nesting in thumb tile * merge main * chore: extend cacheExtent * ignore touch events on scrub label when not visible * scrub label ignore events and hide immediately * auto reload on sync * refactor image providers * throttle db updates --------- Co-authored-by: shenlong-tanwen <139912620+shalong-tanwen@users.noreply.github.com> Co-authored-by: Alex Tran <alex.tran1502@gmail.com>
