* filer: stamp the content MD5 on every SaveInsideFiler write

An entry's ETag falls back to Attributes.Md5, so conditional writers key
IF_ETAG_MATCH off it. SaveInsideFiler carried the looked-up attributes
forward without refreshing the hash, leaving it describing whatever the
previous writer stored: a later conditional write matched the stale hash
and overwrote content that had already changed.

* s3api: give the bucket lifecycle constants and the write route key one definition each

The extended-attribute keys, the XML size cap and the object-write ring key
prefix were each spelled out in two places, so the admin dashboard's copies
could drift from the gateway's. Move them to the packages both sides already
import and alias them where the short local name reads better.

* admin: patch the bucket entry's lifecycle keys instead of rewriting the entry

The save read the bucket entry, edited its extended map and wrote the whole
entry back, guarded by IF_UNMODIFIED_SINCE. Nothing that writes a bucket
entry advances its mtime - not the S3 gateway's patchBucketEntry, not
SetBucketOwner, not SetBucketQuota - so the guard never fired and the stale
snapshot reverted whatever else had changed since the lookup.

Send the PATCH_EXTENDED mutation the S3 gateway already uses for these keys:
the filer re-reads and merges under the bucket path lock, so only the two
lifecycle keys move. That removes the reason for the mtime snapshot, the
verification retry loop and the compensating restore of the cleared day-TTL
rules, which the migration now logs instead.

* s3api: run the delete-lifecycle day-TTL migration through the shared helper

DeleteBucketLifecycleHandler kept its own copy of the read-strip-write
sequence the put handler now shares, including a missing return that let a
ToText failure persist a truncated filer.conf and write a second response.
It also wrote the whole file back unconditionally, reverting any concurrent
edit; the shared helper writes conditionally.

* admin: answer 404 when a lifecycle request names a bucket that does not exist

Every SetBucketLifecycle failure came back as 500, including the lookup miss
for an unknown bucket, so a client or monitor read a caller error as a server
fault and retried it.

* s3api: emit lifecycle XML a client would recognize

Two changes to what MarshalCanonical writes, both visible through
GetBucketLifecycleConfiguration, which replays the stored bytes verbatim:
stamp the S3 namespace on the root, and put a size range under <And>. A
<Filter> carries one predicate, so two size bounds side by side is a shape
AWS does not document. Parsing still accepts either.

* admin: fix the lifecycle editor's handling of stored status, deletes and empty saves

Four things the editor got wrong:

A stored <Status> the S3 API never validated, say 'enabled', left both radio
buttons unchecked, so reading the form threw on a null querySelector result
and Save did nothing. Collapse anything but an exact 'Enabled' to 'Disabled',
which is what the engine already does with it.

Deleting a rule re-rendered an open edit form from the snapshot taken when
editing began, discarding what had been typed; every other transition folds
the form in first.

The Transition warning only matched a bare <Transition>, missing the form
with attributes, self-closed or namespace-prefixed.

Saving an emptied rule list clears the configuration through a path with no
prompt, next to a Delete-all-rules button that asks.

Also collapses the three divergent copies of formatBytes on this page to one.

* filer: stop the day-TTL migration from deleting an operator's path rule

The migration removed every rule under the bucket's path that carried a day
TTL in the bucket's collection. The add path it is retiring used
AddLocationConf, which merged its TTL onto whatever already sat at the
prefix, so a rule can hold operator settings the lifecycle path never wrote -
a disk type, WORM retention, a read-only flag, a placement pin. Deleting the
whole rule to retire its TTL took those with it, leaving objects under that
prefix on defaults nobody asked for.

Delete only rules shaped like ones the add path created from scratch;
anything else keeps its settings and loses just the TTL.

Chris LuandGitHub b7928637a0 refactor(s3api): move Lifecycle XML structs to leaf package lifecycle_xml (#9360)
* refactor(s3api): move Lifecycle XML structs to leaf package lifecycle_xml

The structs S3 PutBucketLifecycleConfiguration parses and the canonical
conversion to s3lifecycle.Rule lived in package s3api, which transitively
imports weed/server (which imports weed/shell). Any caller outside
weed/s3api — the shell, the future lifecycle worker — that wanted to
parse a bucket's lifecycle XML hit an import cycle.

Moves:
  weed/s3api/s3api_policy.go              -> lifecycle_xml/types.go
  weed/s3api/s3api_lifecycle_canonical.go -> lifecycle_xml/canonical.go
  s3api_lifecycle_canonical_test.go       -> lifecycle_xml/canonical_test.go
  s3api_policy_test.go                    -> lifecycle_xml/round_trip_test.go

Renames the public RuleStatus type (was unexported ruleStatus) and adds
small accessor methods (Set/Val/AndSet/TagSet) for fields the s3api
handler needs to read across the package boundary. Adds NewPrefix and
NewExpirationDays constructors so the GET handler can build response
rules without poking at unexported fields. Adds a Tag struct local to
the package so it has zero internal seaweed deps. Adds a one-shot
ParseCanonical(xml []byte) helper for non-server callers.

s3api_policy.go was misnamed — its content is lifecycle XML, not S3
bucket policy. The new package name reflects the actual scope.

* test(s3api/lifecycle_xml): exercise public API in tests

- canonical_test.go's parseLifecycle helper went through xml.Unmarshal
  directly; route it through the package's exported Parse so tests
  validate the public entrypoint.
- round_trip_test.go asserted internal flags (rule.Filter.tagSet,
  rule.Filter.andSet, Transition.set, NoncurrentVersionTransition.set);
  switch to TagSet(), AndSet(), Set() — exercises the public contract
  that downstream callers (s3api handler, future shell command) rely on.
