## Problem
When a `workspaceMember` is updated (e.g., theme/locale/avatar changes),
the `WorkspaceMemberAvatarFileDeletionListener` triggers file deletion.
If the referenced file entity doesn't exist in the database, an
unhandled `EntityNotFoundError` crashes the NestJS server, causing a 502
loop.
## Change
Wrap the file deletion call in a try-catch that gracefully handles
`EntityNotFoundError` as a no-op — if the file doesn't exist, there's
nothing to delete.
Fixes#20191.
