[19.0][MIG] Migrate DMS modules to 19.0

[HaithamSaqr]

Migration of DMS modules from 18.0 to 19.0

This PR migrates the following 7 modules to Odoo 19.0:

• dms — Document Management System (core)
• dms_field — Embedded DMS for any record
• dms_auto_classification — Auto classify documents
• dms_field_auto_classification — Auto classify embedded files
• hr_dms_field — DMS for employees
• web_editor_media_dialog_dms — Use DMS files in HTML editor
• dms_user_role — Link DMS access groups to user roles

Migration Patterns Applied

Field renames in Odoo 19

• res.groups.users → res.groups.user_ids
• res.users.groups_id → res.users.group_ids
• ir.actions.server.groups_id → ir.actions.server.group_ids
• ir.actions.act_window.groups_id → ir.actions.act_window.group_ids

New res.groups.privilege model

• res.groups.category_id removed → replaced with res.groups.privilege_id
  pointing to a new res.groups.privilege record (which keeps the
  category_id → ir.module.category relation).

View / RNG schema strict in 19

• Removed deprecated <group expand="0" string="Group By"> attributes from
  search views (no longer accepted by RNG schema).
• Removed unsupported target="inline" from ir.actions.act_window.

Python ORM changes

• Replaced _where_calc / _apply_ir_rules SQL helpers (removed in 19)
  with the standard ORM search() API in dms_field.

JS / OWL changes

• mail.store.Attachment → mail.store["ir.attachment"].
• web_editor module removed in 19 → web_editor_media_dialog_dms now
  depends on html_editor. JS imports updated accordingly.
• Fixed XPath in OWL inheritances (expr="//div" → expr=".") for the
  now-empty web.KanbanView.Buttons / web.ListView.Buttons templates.

hr model changes

• hr.employee.base removed in Odoo 19 → moved dms.field.mixin
  inheritance to hr.employee and hr.employee.public directly.
• View XPath: <field name="user_id"> → <field name="name"> on
  hr.employee.public form (user_id no longer present in the form view).
• Block name: employee_rights_setting_container →
  employees_setting_container in hr.res_config_settings_view_form.

Tested

All 7 modules install successfully on Odoo 19 CE and basic functionality
works (directory creation, file upload, kanban view, embedded DMS on
partners and employees, auto-classification wizard, HTML editor media
dialog).

Hello @HaithamSaqr, normally the PRs are for a single module, that way is way easier to review the code (it is also OCA common practice 😅). I would recommend you to take a look at the guidelines over here https://github.com/OCA/odoo-community.org/blob/master/website/Contribution/CONTRIBUTING.rst
