Every paid download logged "filing into filebrowser/Music/... failed
(non-fatal): Permission denied". The purchase played in-app but never
appeared in Files. FileBrowser's folders belong to its rootless container
range (host uid 100000, mode 755). This service is host uid 1000, outside
that range, so it can read them but not create files in them.
New container::filebrowser::save_new_file:
- Writes directly when the folder allows it.
- Otherwise writes through `podman unshare`, where that uid range is
ours: to a temp file, then chowned to the folder's owner, set to 0644,
and hard-linked into place. FileBrowser never sees a partial file and an
existing file is never replaced. A missing folder is created and given
its parent's owner. No sudo.
- Keeps the "name (2).ext" de-duplication the RPC did inline.
Checked the unshare script on amishparadise in a scratch folder owned
like FileBrowser's: new folder + file OK, owner/mode right, no clobber,
no temp file left, and the service can read the result.
