Fix duplicate TsFile metric updates

[jt2594838]

Description

Make TsFile metric updates idempotent

• Refactor file metric APIs to accept TsFileResource directly and derive database, region, sequence, size, and file name from the resource.
• Track whether each TsFileResource has been recorded by metrics with an atomic flag, preventing duplicate additions or deletions during compaction and file lifecycle transitions.
• Simplify compaction and DataRegion call sites by removing redundant metric arguments.

Tests

• Extend CompactionUpdateFileCountTest to cover repeated metric updates and mixed sequence/unsequence resource deletion.
• Update existing compaction metric tests for the resource-based API.
