No context for 'buttons',

#### Describe the bug
No context for 'button', 'subtitle', 'message_heading', 'icon_classname', using coderedcms versions 4.1.0, 4.1.1, and 5.0.0 and wagtail 6.4.1.

#### Steps to reproduce
Go to the codered wagtail admin with Logging turned on with 'level': 'DEBUG'

#### Expected behavior
In the error.log expect to see:
Exception while resolving variable 'buttons' in template 'wagtailadmin/tables/title_cell.html'.
Traceback (most recent call last):
File "/home/django/red3/lib64/python3.12/site-packages/django/template/base.py", line 883, in _resolve_lookup

KeyError: 'buttons'
#### Additional context
Add any other context about the problem here.

Reproduce the problem in the CodeRed Wagtail admin with DEBUG logging enabled, using the template path wagtailadmin/tables/title_cell.html from the report. Trace the missing 'buttons', 'button', 'subtitle', 'message_heading', and 'icon_classname' context values, then confirm the intended logging behavior before determining what would count as resolved.
