Injected SQL Formatting Enhancement

[xterao]

Updated the formatting logic for SQL embedded within @Sql annotations to align with the intended indentation inside Java literal strings, rather than relying on the original line position.

Previous PR:
#331

Key Improvements

• SQL alignment:
  SQL content is now indented to match the position after the opening """ (triple-quote) of the string literal.

• Closing quotes alignment:
  The closing """ is automatically placed on a new line, aligned with the first line of the SQL content.

Example

Before Formatting:

@Select
@Sql("""
   /** TopBlock */
   select Count(distinct (x))
      , o.* , log(nbor.nearest
        , /* id */2) AS nearest -- column Line commen
/** From */
   from user""")
Emp selectInjection3(Integer id);

After Formatting:

@Select
@Sql("""
        /** TopBlock */
	SELECT Count(DISTINCT (x))
	       , o.*
	       , log(nbor.nearest
	             , /* id */2) AS nearest -- column Line commen
          /** From */
          FROM user
	""")
Emp selectInjection3(Integer id);
