[MBL-1334] Bind styles when PostCampaignPledgeRewardsSummaryTotalViewController loads

[ifosli]

📲 What

Call bindStyles in viewDidLoad. We usually swizzle view controllers to call bindStyles on viewWillAppear and traitCollectionDidChange, but for some reason, on iOS 16, neither of these trigger bindStyles for this class. I think embedding a view controller's view in a different view controller is preventing viewWillAppear from triggering it, but I'm not sure why traitCollectionDidChange calls bindStyles on iOS 17 but not on iOS 16. Regardless of why, calling bindStyles in viewDidLoad fixes the problem and seems significantly safer.

✅ Acceptance criteria

• Total row in the pledge summary table looks good on iOS 16 as well

LGTM. I'd double-check if this view controller was being correctly added as a child of its parent container, and see if that fixes it, but this change seems harmless anyways.

Ahh, good call! that was the problem! I've added it as a child of the parent and I left the bindStyles call in as well.
