refactor: centralize brand, company info, assets and Persian strings

Phase 1 of turning the game into the company landing page.

- Add src/config/company.js with name, tagline, contact, about and the
  product line, plus a brand palette built around #00a693 (contrast
  checked); placeholders are marked TODO(company).
- Add src/config/assets.js listing every loaded file with its expected
  format; placeholders are marked TODO(asset).
- Move all Persian interface text, dialogue, missions and scenery text
  into src/i18n/fa.js; components and game code read from it.
- Expose the palette as CSS variables (--color-primary and shades) and
  Tailwind colours, and use it for 3D materials and map drawings.
- Fix the arrival line that still called the manager's car a white
  pickup.
- Add tests that block hard-coded Persian text and low-contrast colours.
