Add ResourceBase fields to labeled block CTY values

[victorfrederiknielsen]

Summary

Add meta, disabled, and depends_on fields to labeled block element CTY representations. This enables labeled block references (e.g., resource.aws_account.sandbox.user.admin) to be decoded into []types.ResourceBase fields, completing the round-trip for HCL configurations that reference labeled blocks.

Changes

Core CTY Conversion (convert/convert.go)

• Pass parent resource ID to transformLabeledBlocks to build element reference paths
• Rename elementToCty to elementToCtyWithMeta and populate ResourceBase fields:
  • meta.id with the full reference path (e.g., resource.aws_account.sandbox.user.admin)
  • disabled as false
  • depends_on as empty list
• Use gocty.ToCtyValue for clean meta struct conversion instead of manual CTY construction
• Add addLabelFieldToCtyMap helper to include label field values in CTY output

Tests

• Add TestLabeledBlockCtyStructure to verify CTY includes meta/disabled/depends_on fields
• Add TestLabeledBlockReferenceSlice to test slice references like members = [resource...user.admin]
• Add TestLabeledBlockResourceBaseSlice to verify full round-trip with actual types
• Consolidate test fixtures into valid.hcl for consistency
• Add CloudTeam and CloudCredentials test structs

Test Fixtures

• Update cloud_account.go Name field tag to hcl:"name,label" for proper decoding
• Add cloud_team.go with Members/Lead fields for slice reference tests

Testing Strategy

• All labeled block tests pass (TestLabeledBlock*)
• CTY structure test verifies meta/disabled/depends_on presence
• Slice reference tests verify whole-object references work
• Both named and numeric index access patterns tested
