Update with Image frontend buttons

🔗 Issue

#592

✍️ Description

• Overview: Update the dashboard to allow staff to manage Page Text options, including updating Hero Text, About Us text, and corresponding images on the organization's root/home page.
• Implementation:
  • Utilize PageText model with has_one_attached :hero_image and has_many_attached :about_us_images.
  • Add form inputs for attachments on the PageText form: one clearly labeled for Hero Image (single attachment) and one for About Us images (one or two attachments).
  • Implement model validations for image file type and size restrictions, referencing the Pets Controller for examples.
  • Update PageTextsController to handle image attachments and purging.
  • Ensure staff can upload and purge images.
  • Reuse partials for upload inputs and image display tables, similar to those used in Pet tabs.
  • On the org's root/home page, render the hero_image and one or both about_us_images as applicable, with a default image for the second if only one is uploaded.
• Testing:
  • Modify tests to accommodate changes to the page_text model. Pay special attention to these modifications.

I do not like how the about us images upload but I could use a little feedback

Hey @ErinClaudio the implementation looks good! Just a couple small details to tweak.

For tests, I think we can handle setting up the PageText differently - see my comment on that.
I also think we could add a controller test for uploading an image.

Also, when I run the tests locally, this test keeps failing for me (though in the pipeline it passes, so maybe there's something going on locally for me...does it pass for you locally?

Organizations::PageTextsControllerTest#test_: PATCH #update should update page text.  [test/controllers/organizations/page_texts_controller_test.rb:53]:
Expected: "canine caped crusader"
  Actual: "Eius id minus et."

Good job @ErinClaudio! This is good chunk of work that adds value to the customization of the home page for each org. Thank you for seeing it through!
