Closes [571](https://github.com/twentyhq/core-team-issues/issues/571).
Replicates the behavior of number field and allows specifying the number
of decimals for currency field.

Currencies around the world have a maximum of three decimal places -
BHD, KWD etc. However, I have added a maximum of five decimal places in
case someone wants to use the currency field type for displaying things
like `per-second-billing` or `exchange rates`.

> [!NOTE]
> Adds configurable decimals (0–5) for currency fields, updating
settings UI, types/schema, display/aggregate formatting, and input
precision.
>
> - **Currency field settings**:
> - Add `decimals` (0–5) to `FieldCurrencyMetadata.settings` and
validate via `currencyFieldSettingsSchema`.
> - Update `SettingsDataModelFieldCurrencyForm` to manage `format`
(short/full) and `decimals` with counter when `full`; wire defaults via
`useCurrencySettingsFormInitialValues`.
> - **Display & aggregation**:
> - `CurrencyDisplay` and
`transformAggregateRawValueIntoAggregateDisplayValue` honor `decimals`
when `format` is `full`; keep short format using `formatToShortNumber`.
> - **Input**:
> - Increase currency `IMaskInput` precision with `scale=5`.
