* Refactor EC placement tests to reuse buildActiveTopology
Remove buildActiveTopologyWithDiskTags helper function and consolidate
tag setup inline in test cases. Tests now use UpdateTopology to apply
tags after topology creation, reusing the existing buildActiveTopology
function rather than duplicating its logic.
All tag scenario tests pass:
- TestECPlacementPlannerPrefersTaggedDisks
- TestECPlacementPlannerFallsBackWhenTagsInsufficient

* Consolidate normalizeTagList into shared util package
Extract normalizeTagList from three locations (volume.go,
detection.go, erasure_coding_handler.go) into new weed/util/tag.go
as exported NormalizeTagList function. Replace all duplicate
implementations with imports and calls to util.NormalizeTagList.
This improves code reuse and maintainability by centralizing
tag normalization logic.

* Add PreferredTags to EC config persistence
Add preferred_tags field to ErasureCodingTaskConfig protobuf with field
number 5. Update GetConfigSpec to include preferred_tags field in the
UI configuration schema. Add PreferredTags to ToTaskPolicy to serialize
config to protobuf. Add PreferredTags to FromTaskPolicy to deserialize
from protobuf with defensive copy to prevent external mutation.
This allows EC preferred tags to be persisted and restored across
worker restarts.

* Add defensive copy for Tags slice in DiskLocation
Copy the incoming tags slice in NewDiskLocation instead of storing
by reference. This prevents external callers from mutating the
DiskLocation.Tags slice after construction, improving encapsulation
and preventing unexpected changes to disk metadata.

* Add doc comment to buildCandidateSets method
Document the tiered candidate selection and fallback behavior. Explain
that for a planner with preferredTags, it accumulates disks matching
each tag in order into progressively larger tiers, emits a candidate
set once a tier reaches shardsNeeded, and finally falls back to the
full candidates set if preferred-tag tiers are insufficient.
This clarifies the intended semantics for future maintainers.

* Apply final PR review fixes
1. Update parseVolumeTags to replicate single tag entry to all folders
instead of leaving some folders with nil tags. This prevents nil
pointer dereferences when processing folders without explicit tags.
2. Add defensive copy in ToTaskPolicy for PreferredTags slice to match
the pattern used in FromTaskPolicy, preventing external mutation of
the returned TaskPolicy.
3. Add clarifying comment in buildCandidateSets explaining that the
shardsNeeded <= 0 branch is a defensive check for direct callers,
since selectDestinations guarantees shardsNeeded > 0.

* Fix nil pointer dereference in parseVolumeTags
Ensure all folder tags are initialized to either normalized tags or
empty slices, not nil. When multiple tag entries are provided and there
are more folders than entries, remaining folders now get empty slices
instead of nil, preventing nil pointer dereference in downstream code.

* Fix NormalizeTagList to return empty slice instead of nil
Change NormalizeTagList to always return a non-nil slice. When all tags
are empty or whitespace after normalization, return an empty slice
instead of nil. This prevents nil pointer dereferences in downstream
code that expects a valid (possibly empty) slice.

* Add nil safety check for v.tags pointer
Add a safety check to handle the case where v.tags might be nil,
preventing a nil pointer dereference. If v.tags is nil, use an empty
string instead. This is defensive programming to prevent panics in
edge cases.

* Add volume.tags flag to weed server and weed mini commands
Add the volume.tags CLI option to both the 'weed server' and 'weed mini'
commands. This allows users to specify disk tags when running the
combined server modes, just like they can with 'weed volume'.
The flag uses the same format and description as the volume command:
comma-separated tag groups per data dir with ':' separators
(e.g. fast:ssd,archive).
