chore(deps): bump django-htmx from 1.27.0 to 1.28.0

[dependabot]

Bumps django-htmx from 1.27.0 to 1.28.0.

Changelog

Sourced from django-htmx's changelog.

1.28.0 (2026-07-12)

• Support htmx version 4 <https://four.htmx.org/>__ (beta), available by adding version=4 to the :doc:template tags \<template_tags>. The default htmx version remains 2, since htmx 4 is in beta. When htmx 4 is released, the default will be updated to 4 in a future major release of django-htmx.

  For example, with the Django templates htmx_script tag:

  .. code-block:: django

  {% htmx_script version=4 %}
  

  The :doc:example project <example_project> now uses htmx 4, to demonstrate its usage.

  See the htmx 4 migration guide <https://four.htmx.org/docs#migration>__ for guidance on adopting version 4.

  PR [#606](https://github.com/adamchainz/django-htmx/issues/606) <https://github.com/adamchainz/django-htmx/pull/606>__.

• Extend the request.htmx object with two new attributes based on new htmx-4-only attributes:

  • :attr:HtmxDetails.request_type <django_htmx.middleware.HtmxDetails.request_type>, based on the |HX-Request-Type header|__ that indicates if the request is for full or partial content.
  • :attr:HtmxDetails.source <django_htmx.middleware.HtmxDetails.source>, based on the |HX-Source request header|__ that htmx 4 sends instead of HX-Trigger/HX-Trigger-Name.

  .. |HX-Source request header| replace:: HX-Source request header __ https://four.htmx.org/reference/headers/HX-Source

  .. |HX-Request-Type header| replace:: HX-Request-Type request header __ https://four.htmx.org/reference/headers/HX-Request-Type
