Align IntelliJ IDEA Code Style with checkstyle_check.xml Rules

Description

To maintain consistency between IntelliJ IDEA’s auto-formatting and our Checkstyle rules (checkstyle_check.xml).

This issue will help ensure that developers using IntelliJ can rely on Reformat Code (Ctrl + Alt + L)

✅ Auto-Fixable by IntelliJ IDEA

The following Checkstyle rules are automatically handled by IntelliJ's built-in formatting tools:

• EmptyLineSeparator
• FileTabCharacter
• ImportOrder
• Indentation
• LeftCurly
• LineLength
• MethodParamPad
• NeedBraces
• NoWhitespaceAfter
• NoWhitespaceBefore
• OperatorWrap
• ParenPad
• RedundantImport
• RightCurly
• SeparatorWrap
• SingleSpaceSeparator
• WhitespaceAfter
• WhitespaceAround

Incomplete and abandoned PR is at #16349 feel free to continue it BUT be aware that we migrated to qudana for inspection.
