* 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. Claude-Session: https://claude.ai/code/session_015n3oKLTjnPjcnZtfigNKur * 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. Claude-Session: https://claude.ai/code/session_015n3oKLTjnPjcnZtfigNKur * 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. Claude-Session: https://claude.ai/code/session_015n3oKLTjnPjcnZtfigNKur * 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. Claude-Session: https://claude.ai/code/session_015n3oKLTjnPjcnZtfigNKur * 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. Claude-Session: https://claude.ai/code/session_015n3oKLTjnPjcnZtfigNKur * 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.
