Chris Lu 0345658ea8 [s3] validate indirect filer path inputs (#9931)
* 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.

Chris Lu bb0c7c779f feat(s3/lifecycle): metadata-only delete when entry TtlSec > 0 (Phase 2b) (#9390)
* refactor(s3): thread metadataOnly into delete helpers

Add a metadataOnly bool to deleteUnversionedObjectWithClient and
deleteSpecificObjectVersion. When true the helper sends IsDeleteData=
false to the filer's DeleteEntry RPC so per-chunk DeleteFile RPCs are
skipped — the volume server reclaims chunks on its own at TTL drop.
Non-lifecycle callers (DELETE handlers, batch delete) pass false to
preserve today's eager-chunk-delete behavior; only the lifecycle
handler in the next commit will pass true.

* feat(s3/lifecycle): metadata-only delete when entry TtlSec > 0

Per-write TTL stamping (PR 9377) sets Attributes.TtlSec on every
lifecycle-fitting entry. When the live entry the LifecycleDelete
handler fetched carries TtlSec > 0 the volume server is guaranteed
to reclaim chunks at TTL drop, so the filer can skip per-chunk
DeleteFile RPCs and just remove the entry record. lifecycleDispatch
now computes metadataOnly from the live entry and threads it through
the unversioned, suspended-null, and noncurrent/expired-marker delete
paths. createDeleteMarker is unaffected — it creates a marker, never
deletes chunks.

Chris Lu 995dfc4d5d chore: remove ~50k lines of unreachable dead code (#8913)
* chore: remove unreachable dead code across the codebase

Remove ~50,000 lines of unreachable code identified by static analysis.

Major removals:
- weed/filer/redis_lua: entire unused Redis Lua filer store implementation
- weed/wdclient/net2, resource_pool: unused connection/resource pool packages
- weed/plugin/worker/lifecycle: unused lifecycle plugin worker
- weed/s3api: unused S3 policy templates, presigned URL IAM, streaming copy,
  multipart IAM, key rotation, and various SSE helper functions
- weed/mq/kafka: unused partition mapping, compression, schema, and protocol functions
- weed/mq/offset: unused SQL storage and migration code
- weed/worker: unused registry, task, and monitoring functions
- weed/query: unused SQL engine, parquet scanner, and type functions
- weed/shell: unused EC proportional rebalance functions
- weed/storage/erasure_coding/distribution: unused distribution analysis functions
- Individual unreachable functions removed from 150+ files across admin,
  credential, filer, iam, kms, mount, mq, operation, pb, s3api, server,
  shell, storage, topology, and util packages

* fix(s3): reset shared memory store in IAM test to prevent flaky failure

TestLoadIAMManagerFromConfig_EmptyConfigWithFallbackKey was flaky because
the MemoryStore credential backend is a singleton registered via init().
Earlier tests that create anonymous identities pollute the shared store,
causing LookupAnonymous() to unexpectedly return true.

Fix by calling Reset() on the memory store before the test runs.

* style: run gofmt on changed files

* fix: restore KMS functions used by integration tests

* fix(plugin): prevent panic on send to closed worker session channel

The Plugin.sendToWorker method could panic with "send on closed channel"
when a worker disconnected while a message was being sent. The race was
between streamSession.close() closing the outgoing channel and sendToWorker
writing to it concurrently.

Add a done channel to streamSession that is closed before the outgoing
channel, and check it in sendToWorker's select to safely detect closed
sessions without panicking.
