* webdav: name the entry, not its path, in a listing
DAV:displayname carried the full path of every entry. A client that
takes displayname for the child's name - Windows Explorer does - then
looks for /dir/name under /dir and finds nothing, so a folder shows up
empty while the root, where the two spellings differ only by a leading
slash, still lists.
Readdir now builds its entries with toFileInfo like stat does, so a
listing and a lookup describe a child the same way, and the wrapper that
was trimming the sub-folder back off a name goes away with it.

* webdav: derive an ETag when nothing hashed the entry
Uploads through this gateway carry no content MD5, so filer.ETag comes
back empty and every file in a PROPFIND answered with an empty
DAV:getetag, which is not a valid entity-tag. Report it as unimplemented
instead, the way the sub-folder wrapper already did, and webdav falls
back to modification time and size. The wrapper's copy went with it - it
swallowed the stat error a caller was meant to see.

* s3: validate indirect filer path inputs
* s3: avoid query parsing on common request path
* filer: scope copy/move source against JWT AllowedPrefixes
maybeCheckJwtAuthorization only checked r.URL.Path, but copy and move read
their source from the cp.from / mv.from query params. A prefix-restricted
token could copy or move data out of a subtree it cannot otherwise reach.
Check every path the request touches, reusing pathHasComponentPrefix so
`..` in the source is collapsed before the prefix match.
* s3: confine iceberg CreateTable location to the catalog bucket
CreateTable derived the metadata bucket and path from the client-supplied
req.Location / req.Name and wrote there directly, so a caller scoped to one
table bucket could place metadata in another bucket (and path.Join collapsed
any `..`). Require the parsed bucket to equal the request's catalog bucket
and reject traversal segments in the table path.
* webdav: clean client path before subFolder confinement
wrappedFs concatenated subFolder + name before the underlying FileSystem
ran path.Clean, so `..` in the request path or COPY/MOVE Destination
resolved across the FilerRootPath confinement boundary. Clean the name as a
rooted path first so traversal segments collapse below subFolder. Only the
non-default -filer.path (non-empty subFolder) setup was affected.
* filer: enforce read-only rule on real write path with destination header
The x-seaweedfs-destination header overrides the path used for storage-rule
matching while the entry is written at r.URL.Path, letting a caller select a
writable rule for a read-only target. When the header is present, also check
the read-only/quota rule against the actual write path.
