Resolve merge conflicts with master; rename indent → ident in createCaseMatchClause

[Copilot]

The PR branch had diverged from master, which had already merged resolveCaseIdent into GeneratorHelpers (via a parallel fix) and added a generateModules helper — causing a conflict in GeneratorHelpers.fs.

Changes

• GeneratorHelpers.fs — resolved conflict by removing the duplicate resolveCaseIdent that appeared at the bottom of our branch; retained master's generateModules helper and the canonical resolveCaseIdent placement at the top
• DUCasesGenerator.fs — renamed misleading indent → ident in createCaseMatchClause (the binding holds a SynLongIdent, not indentation):

  // Before
  let indent = GeneratorHelpers.resolveCaseIdent requiresQualifiedAccess parent id
  let p = SynPat.CreateLongIdent(indent, args)
  
  // After
  let ident = GeneratorHelpers.resolveCaseIdent requiresQualifiedAccess parent id
  let p = SynPat.CreateLongIdent(ident, args)
