chore(deps): bump django-treebeard from 4.8.0 to 5.0.2

[dependabot]

Bumps django-treebeard from 4.8.0 to 5.0.2.

Changelog

Sourced from django-treebeard's changelog.

Release 5.0.2 (Feb 13, 2026)

Treebeard 5.0.2 is a bugfix release.

• MP and NS nodes are refreshed from the database after a move, for a better developer experience. Previously it was left to the developer to refresh manually if they needed to use the node, and this was the source of numerous issues.
• Fixed handling of reverse ordering in node_order_by.
• Fixed handling of inherited models in TreeAdmin.
• Fixed adding root nodes for inherited models.
• Handled null values of fields specified in node_order_by more gracefully: ignore the field for the purpose of ordering and log a warning to indicate that the value likely needs to be provided manually.
• Modified dump_bulk() methods to use a queryset iterator to avoid loading large datasets into memory.
• Fixed import error with Django 6 if pyscopg was not installed.

Release 5.0.1 (Feb 11, 2026)

Treebeard 5.0.1 is a bugfix release.

• Fixed count aggregations not working on MariaDB.

Release 5.0.0 (Feb 11, 2026)

Treebeard 5.0 is a major release with a number of significant changes:

• All operations that previously used raw SQL queries were rewritten to use the Django ORM. This provides better security, portability across backends, and compability for multiple database setups.
• An experimental implementation using PostgreSQL Ltree was added.

Backward incompatible changes:

• Internal fields used by Treebeard's MoveNodeForm have been renamed from _position to treebeard_position and _ref_node_id to treebeard_ref_node.
• Changed initialisation signatures for the internal MP_AddChildHandler and MP_AddSiblingHandler to avoid collisions with model field names. Both constructors now expect a mapping of model creation arguments as a single parameter, instead of keywords arguments passed to the constructor.
• MoveNodeForm has been refactored to use a ModelChoiceField for selecting the relative node. This field can be used by projects, e.g., for foreign keys in the Django admin.
• Removed the Node.get_database_vendor() helper function which is no longer used.
• The deprecated destructive argument was removed from MP_Node.fix_tree() use fix_paths instead.

Other changes:

• Added support for Python 3.14.
• Added support for Django 6.0.
