[14.0] XAF Audit file improvements

[CasVissers-360ERP]

Hi all,

Have some improvements which I think could be beneficial:

1. Do not included move lines with a display_type:
   <trLine t-foreach="m.line_ids" t-as="l"> ->>> <trLine t-foreach="m.line_ids.filtered(lambda l: not l.display_type)" t-as="l">
2. Add state checks:
   add "and parent_state = 'posted' ", to queries:
   get_move_line_total_credit
   get_move_line_total_debit
   get_move_line_count
   get_ob_totals
   EDIT: There is a PR for this: [14.0][FIX] Only include move lines that have been posted in the SQL queries #325

@antonioburic your work on the module triggered me with some improvements I had in mind.
