feat: allow custom thousands separator per team and apply in currency…

[nachoaguirre]

Summary

This PR adds support for configurable thousands separator in currency formatting across the application.

Changes

• Currency Filter: Added thousandsSeparator parameter to formatCurrency() function with default value ,
• Team Model: Added thousands_separator field to store user preference (defaults to ,)
• Team Settings UI: Added input field in the Invoicing tab to configure the thousands separator
• Components: Updated all invoice-related components to use the configured separator from team settings:
  • InvoiceRow.vue
  • InvoiceHeader.vue
  • InvoiceTotals.vue
  • InvoicesList.vue
• Store: Updated invoices.js to include thousands_separator in the team properties mapping
• i18n: Added translation key for the new setting

Usage

Users can now configure their preferred thousands separator (comma, space, period, etc.) in the Team Settings > Invoicing tab. The separator will be applied to all currency values throughout the application.

Examples:

• , → 1,234,567.89
• (space) → 1 234 567.89
• . → 1.234.567.89
• `` (empty) → 1234567.89

Technical Notes

• Backward compatible: defaults to comma separator if not configured
• Uses component methods instead of filters to access Vuex store state
• Compatible with older Babel versions (no optional chaining operators)
