refactor(inc, image-optimizer): restructure /inc architecture and standardize image optimizer module

- reorganized /inc directory structure for improved separation of concerns
  - grouped files into customizer, utilities, and tools
  - improved naming consistency across files (e.g. *-settings, template-tags, etc.)
  - simplified functions.php includes for better readability and maintainability

- refactored Customizer structure
  - extracted image optimizer settings from core-settings into dedicated module
  - consolidated settings, UI logic, and styles into a single feature file
  - improved naming consistency for hooks and functions

- standardized Image Optimizer admin tool
  - renamed "Performance Tools" to "Image Optimizer" across UI and hooks
  - updated admin page registration, callback names, and menu labels
  - aligned AJAX nonce naming for consistency and clarity

- preserved all existing logic and behavior (no functional changes)
- improved overall code organization and long-term maintainability

no breaking changes
