Add page render tests for Blog, Breads, Locations, Recipes, People, and Search apps

[vikram-2101]

Summary

Currently, only the HomePage model has test coverage (bakerydemo/base/tests/test_home_page.py).
The following apps have zero tests:

• blog — BlogIndexPage, BlogPage
• breads — BreadsIndexPage, BreadPage
• locations — LocationsIndexPage, LocationPage
• recipes — RecipeIndexPage, RecipePage
• people — (People section, being added in People section of the site #567)
• search — search view

Problem

Without test coverage, regressions can go unnoticed during the ongoing redesign work.
Given that this project is moving towards a larger-scale demo (#566), a reliable test
suite becomes increasingly important.

Proposed Solution

Add a tests/ directory to each app (following the existing pattern in bakerydemo/base/tests/)
and write WagtailPageTestCase tests for each page type. At a minimum, each test should verify:

1. The page renders with HTTP 200
2. The correct template is used
3. Key content from the page is present in the response

Example (following the existing HomePageRenderTest pattern):

# bakerydemo/blog/tests/test_blog_page.py
from wagtail.models import Page, Site
from wagtail.test.utils import WagtailPageTestCase
from bakerydemo.blog.models import BlogIndexPage, BlogPage

class BlogIndexPageRenderTest(WagtailPageTestCase):
    def test_blog_index_renders(self):
        ...  # assert status 200, correct template

I really like this idea but would this be considered part of the demo redesign project and from what they proposed in the redesign issue it seems more of a remake than a redesign meaning most templates may not be used in the redesign but testcase should absolutely be added in the redesigned version.

Planning to include WagtailPageTestCase tests alongside the People and Press Release page types as I build them out for #566 — happy to coordinate so we don't overlap.

I'd like to add tests for the search view (bakerydemo/search/views.py), which ties directly into my work on #665 (preserving fallback search ordering). I'll follow the WagtailPageTestCase pattern from base/tests/ and cover HTTP 200 rendering, correct template usage, and ordering behaviour for the fallback search path.

I'd like to add render tests for Blog, Breads, Locations, and Recipes — following the WagtailPageTestCase pattern. Will open a PR shortly.
