Add the ability to choose the currency symbol

[PatBriPerso]

I need to have billing plans in euro (€) so I add a currency symbol for each plan in the database.

[Copilot]

Pull Request Overview

This PR adds support for custom currency symbols in billing plans to enable pricing in different currencies like euros (€). The implementation adds a new currency column to the plans table and updates the UI to display the configurable currency symbol instead of the hardcoded dollar sign.

Key changes:

• Added database migration to include a currency column in the plans table with a default value of '$'
• Updated Blade templates to display the plan's currency symbol instead of hardcoded '$'
• Enhanced the Filament admin interface to allow editing and viewing the currency field

The currency field should have input validation to ensure only valid currency symbols are entered. Consider adding a validation rule or using a Select component with predefined currency options.

@bobbyiliev, it could be a good idea to have a currency list but with symbols not the 3 letters codes.

Before I do this PR, I see Laravel libs that has all the world currency symbols but it seems to be too much imo (100+ currencies).
To keep it simple, I can just add a few symbols like $, €, £ and ¥. What do you think?

I can also, may be, reduce the size of the column to 1 character (or 3 if we put the code later). What do you think?

This looks great! I'll be reviewing today and tomorrow to do a final check and get this merged in. Appreciate it @PatBriPerso

I push 2 more commits:

• add a few symbols $, €, £ and ¥ in a select list for edit/new plan forms
• change migration to reduce the size of the column to 3 characters
