[Bug]: occ share:list aborts with "Node for share not found" if any orphaned share exists

Bug description

occ share:list aborts with exit code 1 and produces no output at all as soon as a single orphaned share exists (a row still present in oc_share whose file id can no longer be resolved):

In Share.php line 169:
  Node for share not found, fileid: 275263

One orphaned share makes the whole command unusable, e.g. for scheduled exports of all shares.

Orphaned shares are easy to accumulate in practice: they are left behind when a shared file is deleted directly on the storage (external storage / SMB) and also when a shared file is moved to the trash bin (shares are not removed on trashbin deletion, and DeleteOrphanedSharesJob only cleans them up once the file id is gone from the file cache completely).

Steps to reproduce

1. Share a file (e.g. a public link share)
2. Delete the file bypassing Nextcloud (e.g. directly on the storage / via SMB), then run occ files:scan so the file cache entry is removed. The row in oc_share remains (orphaned share).
3. Run occ share:list

Expected behavior

The command lists the shares it can resolve; orphaned shares are skipped or marked instead of aborting the whole command.

Additional info

Probable cause: in apps/files_sharing/lib/Command/ListShares.php, execute() maps every share through $share->getNode()->getPath() without handling the NotFoundException thrown by Share::getNode() when the file id cannot be resolved. Still the case on current master. The command was introduced in Nextcloud 32 (#51399).
