chore: add integrate Stylelint for CSS linting (#3909)
# Description of Changes

**What was changed**  
- Added a new `.stylelintrc.json` to configure Stylelint with
`stylelint-config-standard` and custom ignore rules.
- Created a `lint:css` script in `package.json` and added
`stylelint`/`stylelint-config-standard` to `devDependencies`.
  - Added `package-lock.json` to lock dependencies.  
- Updated numerous CSS files under
`stirling-pdf/src/main/resources/static/css/` to fix lint errors
(shorthand properties, removed redundant units, consistent box-shadow
syntax, margin shorthand, etc.).

**Why the change was made**  
- To enforce consistent, modern CSS code style across the project, catch
errors early, and enable automated fixing of common lint issues.
