Fix add new game: reset form on section load, add prominent Add New Game button

- resetGameForm() now called every time Game Management section is opened,
  preventing stuck edit state (disabled slug, wrong form title)
- Added prominent Add New Game button at top of section (master admin only)
- DOMContentLoaded init ensures form state is correct on page load
