feat(mobile): sqlite asset viewer (#19552)
* add full image provider and refactor thumb providers * photo_view updates * wip: asset-viewer * fix controller dispose on page change * wip: bottom sheet * fix interactions * more bottomsheet changes * generate schema * PR feedback * refactor asset viewer * never rotate and fix background on page change * use photoview as the loading builder * precache after delay * claude: optimizing rebuild of image provider * claude: optimizing image decoding and caching * use proper cache for new full size image providers * chore: load local HEIC fullsize for iOS * make controller callbacks nullable * remove imageprovider cache * do not handle drag gestures when zoomed * use loadOriginal setting for HEIC / larger images * preload assets outside timer * never use same controllers in photo-view gallery * fix: cannot scroll down once swipe with bottom sheet --------- Co-authored-by: shenlong-tanwen <139912620+shalong-tanwen@users.noreply.github.com> Co-authored-by: Alex <alex.tran1502@gmail.com>pull/19644/head^2
