[HOLD for payment 2024-05-02] [$750] [CRITICAL] Create a reusable and stylable `MoneyRequestAmountInput`

[youssef-lr]

Problem

the MoneyRequestAmountForm is currently designed to be used from the Amount pages where it is displayed in a view that takes up the whole page, and has specific style for that. We'd like to reuse this input without any extra style and be able to re-style it with ease.

Solution

Decouple the logic that handles accepting and formatting amounts from MoneyRequestAmountForm, by creating a new MoneyRequestAmountInput that doesn't have any custom styles and looks like a basic input.

1. Move all the logic for handling input from MoneyRequestAmountForm into the new input.
2. The MoneyRequestAmountForm should only keep navigation and form logic.
3. The input should have a new callback onAmountChange that can be used by parent components.
4. Display currency as part of the input as in the mocks. For this we can simply use the prefixCharacter that should be prop drilled into the underlying TextInput used in this component. We will need to configure the padding of the prefix text to accomodate for both single character currencies and 3 characters currencies. (e.g. $ and AED). Since the prefix is absolutely positioned, this is necessary.
5. The new input should accept styles so that it can be reused from the Amount full pages, e.g. no borders, increased font, etc.

Here's a mock of how the input should look like when used from the Splits page:

Proposal

Please re-state the problem that we are trying to solve in this issue.

CRITICAL] Make MoneyRequestAmountForm reusable and stylable

What is the root cause of that problem?

New feature

What changes do you think we should make in order to solve the problem?

To fix this issue we need make changes following instructions

For this we need make MoneyRequestAmountInput for this input using input from MoneyRequestAmountForm

App/src/pages/iou/steps/MoneyRequestAmountForm.tsx

Lines 307 to 334 in 5a0e410

	<TextInputWithCurrencySymbol
	formattedAmount={formattedAmount}
	onChangeAmount={setNewAmount}
	onCurrencyButtonPress={onCurrencyButtonPress}
	placeholder={numberFormat(0)}
	ref={(ref) => {
	if (typeof forwardedRef === 'function') {
	forwardedRef(ref);
	} else if (forwardedRef?.current) {
	// eslint-disable-next-line no-param-reassign
	forwardedRef.current = ref;
	}
	textInput.current = ref;
	}}
	selectedCurrencyCode={currency}
	selection={selection}
	onSelectionChange={(e: NativeSyntheticEvent<TextInputSelectionChangeEventData>) => {
	if (!shouldUpdateSelection) {
	return;
	}
	const maxSelection = formattedAmount.length;
	const start = Math.min(e.nativeEvent.selection.start, maxSelection);
	const end = Math.min(e.nativeEvent.selection.end, maxSelection);
	setSelection({start, end});
	}}
	onKeyPress={textInputKeyPress}
	isCurrencyPressable={isCurrencyPressable}
	/>

Also we need remove some function from MoneyRequestAmountForm and use them inside MoneyRequestAmountInput

And if necessary, add a few new parameters

What alternative solutions did you explore? (Optional)

NA
