Fix terragrunt module to properly handle TerragruntArgs and TerraformArgs

[james00012]

Fixes #1609

This PR fixes the terragrunt module to properly handle TerragruntArgs and TerraformArgs, and updates compatibility for Terragrunt v0.93.5+.

Terragrunt Module Changes

Argument Handling:

• Implement proper argument ordering: TerragruntArgs → --non-interactive → command → TerraformArgs
• Replace GetCommonOptions/GetArgsForCommand with buildTerragruntArgs() for consistent argument construction
• Remove deprecated -- separator approach that no longer works in newer Terragrunt versions

v0.93.5 Compatibility:

• Update command syntax from deprecated run-all <cmd> to new <cmd> --all format:
  • ApplyAll: apply --all
  • DestroyAll: destroy --all
  • PlanAllExitCode: plan --all

Stack Commands:

• Fix flag placement in stack output (-json flag now appears after command, not in TerragruntArgs)
• Fix --no-color flag format for proper parsing
• Add TerraformArgs support to stack commands

Terraform Module Changes

Terragrunt Command Updates:

• Add --non-interactive flag automatically for all Terragrunt commands (v0.93.5+)
• Remove terraform-specific flags (-input=false, -auto-approve) from TgApplyAllE and TgDestroyAllE that are not supported by Terragrunt run-all commands

ValidateInputsE Function:

• Update from deprecated validate-inputs to new hcl validate --inputs command (Terragrunt v0.88.1+)
• Update TestExtraArgsHelp to handle new command format in help output

CI Updates

• Update Terragrunt version from v0.80.4 to v0.93.5 in CircleCI config

Testing

All previously failing tests now pass:

• ✅ TestTgApplyAllTgError
• ✅ TestTgApplyAllError
• ✅ TestTgApplyUseLockNoError
• ✅ TestExtraArgsHelp
