Check forms in coding style

Extend coding style tests to check forms:

* [Method Name Is Prefixed With Portal Or Meta Type, Class Or Interface](https://www.erp5.com/documentation/developer/guideline/programming/erp5-Guideline.Programming.Naming.Conventions/#method-name-is-prefixed-with-portal-or-meta-type,-class-or-interface) / [Set Document Form Ids To PortalType_view](https://www.erp5.com/documentation/developer/guideline/module/erp5-Guideline.Module.Creation/#set-document-form-ids-to-portaltype_view) - this was checked for python scripts, but not yet for dialogs
* [Form Name Uses Lowercase View After Portal Type](https://www.erp5.com/documentation/developer/guideline/programming/erp5-Guideline.Programming.Naming.Conventions/#form-name-uses-lowercase-view-after-portal-type)
* [Dialog Form Name Is Postfixed With Dialog](https://www.erp5.com/documentation/developer/guideline/programming/erp5-Guideline.Programming.Naming.Conventions/#dialog-form-name-is-postfixed-with-dialog)
* [Report Name Uses Portal Type Followed By View Report Name And Report](https://www.erp5.com/documentation/developer/guideline/programming/erp5-Guideline.Programming.Naming.Conventions/#report-name-uses-portal-type-followed-by-view-report-name-and-report)
* [Place Simulation And Validation Fields At Bottom Of Right Group](https://www.erp5.com/documentation/developer/guideline/module/erp5-Guideline.Module.Creation/#place-simulation-and-validation-fields-at-bottom-of-right-group)
* [Use Correct Names For Simulation And Validation Titles](https://www.erp5.com/documentation/developer/guideline/module/erp5-Guideline.Use.Correct.Names.For.Simulation.And.Validation.Titles)

and apply minimal fixes to all business templates already running coding style checks.
