* admin: move volume-server read JWT helper into dash
The Iceberg data preview page needs the same per-fileId read token the
file browser uses when streaming chunks from volume servers.

* admin: add Iceberg table data preview page
The admin UI browses the Iceberg catalog down to table details but not
the data itself. Add a Browse Data page per table that walks the
selected snapshot's manifests and shows sample rows from its Parquet
data files, plus the data file list with per-file preview, a snapshot
switcher, and a row limit selector.
Rows are read through a ranged ReaderAt over stream-content so only
the Parquet footer and needed pages are fetched, with the volume read
JWT applied when configured. Iceberg locations resolve into /buckets
with traversal guards, and the file parameter must match a
manifest-listed data file. Snapshots with delete files get a warning
that raw rows are shown.

* admin: integration test for Iceberg catalog and data preview pages
Starts a weed mini cluster with the admin UI, creates a table bucket,
namespace, and tables via the S3 Tables manager, uploads real Parquet
files via S3, writes manifests and snapshots with iceberg-go, and
asserts on the rendered pages: catalog browsing, table details,
current and historical snapshot previews, per-file preview, row
limits, unknown snapshot and file errors, and a metadata-less table.

* admin: write Iceberg preview chunk reads straight into the caller slice
ReadAt wrapped the caller's buffer in a bytes.Buffer, which would
silently allocate a fresh backing array and drop bytes if it ever grew.
Copy directly into the destination slice and reject negative offsets so
the ReaderAt contract holds.

* admin: link to snapshot history when the preview switcher truncates
The snapshot switcher caps at 25 entries; add a trailing item pointing
at the table details page so older snapshots stay reachable.

* test: hoist mini cluster context assignment out of the goroutine
Set MiniClusterCtx before launching the cluster goroutine and clear it
in stop(), so the assignment is not buried in the command loop.

* Respect filerGroup in admin discovery
Admin discovery previously queried master cluster nodes with an empty filer group, so filers registered under a non-default group could not appear in the admin UI. Add an admin filerGroup flag and carry it through cluster-node discovery requests while preserving the empty default behavior.
Constraint: SeaweedFS master ListClusterNodes filters by exact filer_group.
Rejected: Discover all groups implicitly | no existing admin or shell behavior exposes cross-group discovery.
Confidence: high
Scope-risk: narrow
Directive: Keep admin cluster discovery scoped to the configured filerGroup unless an explicit all-groups API is added.
Tested: docker run --rm -v "$PWD:/src" -w /src golang:1.25 go test ./weed/admin/dash -run TestListClusterNodesRequest -count=1
Tested: docker run --rm -v "$PWD:/src" -w /src golang:1.25 go test ./weed/command -run '^$' -count=1
Not-tested: full repository test suite
* mini: pass filer group to admin cluster discovery
miniAdminOptions.filerGroup was never initialized, so startAdminServer
dereferenced a nil *string. Share the filer.filerGroup flag pointer so the
co-located admin queries the same group the filer registers under.

* fix(admin): switch file browser upload/download to filer gRPC + volume HTTP
The admin file browser proxied uploads and downloads through the filer's
HTTP listener, so the whole feature 404'd against filers started with
-disableHttp=true even though S3 still worked on its own port. Re-route
through the filer gRPC service: LookupDirectoryEntry + StreamContent for
reads (chunks flow straight from the volume servers), AssignVolume +
volume HTTP POST + CreateEntry for writes. Volume read tokens come from
jwt.signing.read.key when configured; the old jwt.filer_signing tokens
no longer apply since the filer HTTP surface is bypassed.
* admin file browser: propagate request context + track response writes
Pass r.Context() into uploadFileToFiler so a client disconnect cancels
the in-flight chunked upload instead of letting it run to completion
against the volume servers. For DownloadFile, replace the Content-Type
probe with a small response-writer wrapper that records whether headers
or bytes have actually been sent, so the error path can't silently
convert a pre-stream failure into a partial response if future code
moves the header-setting around.
