Motivation Avoid full-table scans and high-memory iterations when checking mountpoints by using a targeted lookup instead of iterating all folders. Reduce global table reads for applicable/group mappings by scoping queries to only requested folder IDs. Description Replace loop-based mountpoint existence check in lib/Controller/FolderController.php with a call to FolderManager::mountPointExists() to perform a single targeted query. Add mountPointExists() to lib/Folder/FolderManager.php to check for a mount point using a single-row query. Introduce getApplicableForFolders() and getApplicableForFolder() and getFolderMappingsForFolders() in lib/Folder/FolderManager.php to fetch applicable groups/circles and manage mappings for a specified list of folder IDs. Update getAllFoldersWithSize(), getAllFoldersForUserWithSize(), getFolder(), getGroups(), and getCircles() to use the new scoped helpers instead of loading all applicable/mapping rows, including safe early-return when the folder ID list is empty.
