[White label] Substitute "HCB" for Organization name on donation page

[garyhtou]

When white labeling is enabled, it should do the following on the donation page:

• Instead of saying "HCB", it should just have the organization name.
  • Anywhere on the page
  • The page title
  • Don't worry about the code itself or any non-visible text (e.g. HTML)
• Remove the "fiscally sponsored by" message at the bottom of the page.

Make this an organization setting.

Implementation

This is really important. The rails app should have a nice way to determine:

1. Whether this page is white-labeled or not (which depends on the organization)
2. If the page is white-labeled, it should know what name to use. If not white-labeled, fallback to "HCB'.

In other words, abstract out the logic for this so we don't need to handle it in every view. Here's a very simple non-production-ready version of what I'm talking about:

module ApplicationHelper
  def white_labeled?
    @white_label && @event&.white_label?
  end

  def platform_name(fallback: "HCB")
    white_labeled? ? @event.name : fallback
  end
end

class DonationController
  before_action { @white_label = true }
end

Donation page by <%= platform_name %>

I think we need to be transparent about a nonprofit's legal status when people are making donations:

Remove the "fiscally sponsored by" message at the bottom of the page.

If anyone is planning to take this on, before writing code for this ticket, please chat with me first so we have a solid plan on what the UX will look like. As Sam said, we need to make sure some legal information is clear.
