Fixes WOOMOB-1864

Description

Fixes the linked issue by constraining the moreDetailsContainerView to the keyboardLayoutGuide.topAnchor instead of setting the contentInset via KeyboardFrameObserver.

Test Steps

1. Log in to any store that has orders.
2. Tap a product in the "Top performers" card.
3. Tap in the title to edit.
4. Note that when the keyboard opens, the title is still visible.

I tested it on iPad, iPhone 17 and iPhone SE simulators. Tried increasing the accessibility font to make it hard for title field to fit with opened keyboard. Worked well.

I wonder if enabling the automatic table view inset adjustment would also solve the issue. Currently it's disabled tableView.contentInsetAdjustmentBehavior = .never

But since it works - I'm ok. LGTM
