IDEMPIERE-4781 : Dashboard / Report : use @SQL= syntax (#677)

* IDEMPIERE-4781 : Dashboard / Report : use @SQL= syntax

* IDEMPIERE-4781 : Dashboard / Report - be able to use Range parameters

* IDEMPIERE-4781 : Dashboard Content as Advanced

* Update DashboardController.java

Implement partial solution for IDEMPIERE-4779

Fix issue with Timestamp not working for IDEMPIERE-4781
it was throwing:
12:58:07.928-----------> DashboardController.render: Failed to create dashboard content [358]
java.lang.NumberFormatException: Error at index 6 in: "474671+02"
	at java.base/java.lang.NumberFormatException.forCharSequence(NumberFormatException.java:81)
	at java.base/java.lang.Integer.parseInt(Integer.java:735)
	at java.sql/java.sql.Timestamp.valueOf(Timestamp.java:239)
