style: Apply new gobo rules

[EttyKitty]

Summary by cubic

Apply the new gobo formatting rules across the GML codebase and add .goborc.json. Changes are stylistic for readability and diff quality; a few safe call-site fixes were made to pass undefined for optional args.

• Refactors

  • Added .goborc.json (4-space indent, vertical arrays/structs, trailing commas, blank lines after blocks, explicit undefined for optional args).
  • Ran the formatter across objects/scripts; no behavior changes intended.

• Bug Fixes

  • Replaced missing/omitted parameters with undefined in helper calls (e.g., determine_pdf_defence(...), draw_unit_buttons(...)) to prevent runtime issues and clarify intent.

Shadow auto-approve: would auto-approve. All changes are either formatting (blank lines, commas, spacing) enforced by the new gobo config, or the addition of explicit undefined for omitted optional arguments, which is semantically equivalent and safe.
