There is no good reason to prevent editing in cancelled state and
it can be needed, for example to remove a cancelled payment
transaction from a payment transaction group.

Ran https://github.com/python/cpython/blob/3.7/Lib/lib2to3/fixes/fix_asserts.py after adding the missing methods (assertRegex and assertRaisesRegex) on ERP5TypeTestCase.

Also ran a custom fixer rewriting
 
```py
self.assertTrue(a in b)
```

into

```py
self.assertIn(a, b)
```

Unindexation happens in a transation after the corresponding document was
deleted. So there is no context available to check the type of the deleted
document. So these filter expressions are meaningless.

The add-hoc assertin filter:

class FixAssertIn(BaseFix):

      ')' > >

  def transform(self, node: lib2to3.pytree.Node,
                results: List[lib2to3.pytree.Base]):

    needle = results['needle']
    haystack = results['haystack']
    meth = results["meth"][0]

    method_map = {True: 'assertIn', False: 'assertNotIn'}
    method_in = meth.value == 'assertTrue'
    if 'not' in str(needle.parent.children[1]):
      method_in = not method_in
    meth.replace(Name(method_map[method_in], prefix=meth.prefix))

    needle.parent.children = [needle, Comma(), haystack]

so that we can run 2to3.fix_assert

This updates the change to 32cead86 (xhtml_style: set a bottom
margin for dialog action, 2019-05-31) that got impacted by a rule
added on html and body in 5dde17a5 (xhtml_style: make editors in
bottom group use full height, 2022-08-22)

this code was latin 1, causing issues for refactoring scripts

Form.__call__ replaces page template call, so it is also responsible
to set the content type in response.

With Page Templates, ZopePageTemplate._exec (called by
Shared.DC.Scripts.Bindings.__call__ and _bindAndExec) sets the
response content type and calls pt_render. Form.__call__ also calls
pt_render, so to behave like page template, it should also sets the
response content type.

In erp5_xhtml_style, we don't notice this, because global_definitions
contains a setHeader call to set content type to html.

Check that it correctly includes the web page and sets the content
type header.

it would be good to rewrite this in a page template

This method converts the HTML, so it should escape nasty HTML tags.

Also add missing escaping when inserting the base

and move it to erp5_administration, this is not a "core" feature but
just a developer tool.

It was used in a few tests, move all the tests in testERP5Administration

Make sure we don't set grouping reference on lines that have a valid
group only for source (or destination) but not for the other side.

gadget_html_viewer had styles to add a border for tables, so that they
look similar to tables added in CKEditor. One problem is that all tables
had borders, because HTML emails are often using tables to position the
content, when viewing an Mail Message from ERP5 back office interface
we could see all the borders, which looked a bit ugly.

These changes bring back a behavior closer to default style sheet of
browsers: tables have no border by default, but a rule is added to
emulate the rendering of border="1" attributes, so that tables edited
with CKEditor have borders and look the same in the editor or in the
html viewer.
