Add support for setting dynamic suffix on MetricCard (e.g., currency)

[jetienne]

Feature

I would like the ability to dynamically set the suffix on a MetricCard based on the resource or record being displayed. For instance, when displaying a monetary amount, the suffix should reflect the currency of the related record.

Use case:
In my current use case, we display the total amount of a Deal, and I need to append the correct currency symbol (e.g., $, €, etc.) to the value shown on the MetricCard. However, it seems there is currently no way to access the resource or record within the MetricCard to set the suffix dynamically.

Here's a proposed solution:

class Avo::Cards::Revenue < Avo::Cards::MetricCard
  self.suffix = = lambda { resource.record.currency }
