[fix](storage) avoid duplicate exported compaction metrics

[CSoulode]

issue: #60791

Add missing labels for compaction task state and compaction io metrics to avoid duplicate Prometheus time series.

What problem does this PR solve?

Issue Number: close #60791

Related PR: #N/A

Problem Summary:

This PR fixes duplicate Prometheus time series exported by BE compaction metrics.

Although issue #60791 was reported in compute-storage decoupled mode, the root cause is not specific to cloud mode itself. The duplicate series come from shared BE metric definitions/export semantics, where multiple internal metrics were exported with the same metric name and the same label set.

Check List (For Author)

• Test
  • Regression test
  • Unit Test
  • Manual test (add detailed scripts or steps below)
  • No need to test or manual test. Explain why:
    • This is a refactor/code format and no logic has been changed.
    • Previous test can cover this change.
    • No code files have been changed.
    • Other reason

Manual test:

1. Start a local Doris cluster and prepare a tablet with compaction candidates.
2. Trigger cumulative compaction:

curl -X POST "http://$BE_HOST:$BE_HTTP/api/compaction/run?tablet_id=$TABLET_ID&compact_type=cumulative"

3. Check exported compaction task metrics:

curl -s "http://$BE_HOST:$BE_HTTP/metrics" \
  | grep '^doris_be_compaction_task_state_total' \
  | sed -E 's/ [^ ]+$//' \
  | sort \
  | uniq -c

Before:

2 doris_be_compaction_task_state_total{type="base"}
2 doris_be_compaction_task_state_total{type="cumulative"}

After:

1 doris_be_compaction_task_state_total{state="pending",type="base"}
1 doris_be_compaction_task_state_total{state="pending",type="cumulative"}
1 doris_be_compaction_task_state_total{state="running",type="base"}
1 doris_be_compaction_task_state_total{state="running",type="cumulative"}

• Behavior changed:

  • No.
  • Yes. The exported metric labels in /metrics are changed to avoid duplicate Prometheus series.

• Does this need documentation?

  • No.
  • Yes.
