fix: resolve CI linting issues for Astroglobe

Fix all ESLint, Stylelint, PHP CS Fixer, and Psalm workflow errors.

Changes:
- ESLint fixes:
  - Remove unused APP_NAME constant
  - Remove unused TextBoxOutline and TextBoxRemoveOutline components
  - Remove unused container variable in adminSettings.js
  - Auto-fix trailing commas, line breaks, attribute ordering
- PHP CS Fixer:
  - Add trailing commas after last function parameters
  - Convert double quotes to single quotes in log messages
  - Remove unused NoCSRFRequired import
  - Fix arrow function formatting
- Stylelint:
  - Update config to use @nextcloud/stylelint-config
  - Fix extends directive (was using non-existent package)
- Psalm workflow:
  - Fix jq object indexing (.include[0] instead of .[0])
  - Correctly extract OCP version from matrix output

All checks now pass locally.
