Compact CTE formatting and apply table name format to CTE definitions

[kinnell]

Description

This PR serves to simplify CTE formatting by removing the keyword-column-aligned padding and applying table name formatting to CTE definition names.

Previously, the with keyword was padded to the keyword column width (e.g. with ), CTE body lines were indented from the keyword column, the closing paren was placed at the keyword column, and subsequent CTE definitions were aligned to the keyword column. This produced deeply indented CTE bodies that drifted far to the right, especially with wider keyword column widths or nested CTEs.

The with prefix is now compact (with ), CTE body lines are indented by indent_spaces from column zero, and the closing paren sits at column zero. CTE definition names also now follow the table_name_format setting (PascalCase by default), matching how CTE references were already formatted in FROM clauses.

Pull request overview

This PR updates how Common Table Expressions (CTEs) are rendered by SqlBeautifier, making WITH formatting compact (no keyword-column padding) and applying table_name_format to CTE definition names so CTE headers match how CTE references are formatted elsewhere (e.g., in FROM).

Changes:

• Switch CTE rendering to a compact with prefix and indent CTE bodies by indent_spaces from column zero (with the closing ) at column zero).
• Apply table_name_format to CTE definition names in WITH ... AS ( headers (while preserving quoted identifiers).
• Update/extend specs and add changelog notes to reflect the new formatting behavior.
