[NT-1340] Expandable Rewards Pledge View Header

[justinswart]

📲 What

Adds the new expanded reward header to PledgeViewController.

Note: Subsequent PR's will add the expand/collapse functionality. Also, currently only the reward will be shown as there are no add-ons yet.

🤔 Why

A continuation of the work that we're doing for add-on rewards, this allows us to display a list of rewards and add-ons on the pledge view.

🛠 How

• Added PledgeExpandableRewardsHeaderViewController and PledgeExpandableRewardsHeaderDataSource.
• Added cells PledgeExpandableHeaderRewardHeaderCell and PledgeExpandableHeaderRewardCell.
• Added VM tests, snapshot tests.

✅ Acceptance criteria

• Navigate to the pledge view, observe the new header is displayed for regular rewards (not No Reward rewards).
• Navigate through the various manage contexts and observe that this header is only shown when in Update pledge, none of the other contexts.

In the future it might be worth standardizing the styles across the whole app.

If its a single line, I think you can just do:

Suggested change

	private lazy var amountLabel: UILabel = { UILabel(frame: .zero) }()
	private lazy var amountLabel: UILabel = UILabel(frame: .zero)

Ah cool, we've always just written our lazy props this way but no reason to add closures if it's not needed! Will update here 👍

[jgsamudio]

Suggested change

	private lazy var rootStackView: UIStackView = { UIStackView(frame: .zero) }()
	private lazy var rootStackView: UIStackView = UIStackView(frame: .zero)

[jgsamudio]

Suggested change

	private lazy var titleLabel: UILabel = { UILabel(frame: .zero) }()
	private lazy var titleLabel: UILabel = UILabel(frame: .zero)
