fix: updating names from enum to human readable description (#270)

### TL;DR

Updated payment rail names from snake_case constants to human-readable display names across all currency configurations.

### What changed?

Converted payment rail identifiers from technical constants to user-friendly display names:
- `FEDNOW` → `FedNow`
- `WIRE` → `Wire` 
- `SEPA_INSTANT` → `SEPA Instant`
- `FASTER_PAYMENTS` → `Faster Payments`
- `BANK_TRANSFER` → `Bank Transfer`
- `MOBILE_MONEY` → `Mobile Money`
- `PAYNOW` → `PayNow`

This affects both `instantRails` and `allRails` arrays across all 22 supported currencies in the grid visualizer.

### How to test?

1. Load the grid visualizer component
2. Verify that payment rail names display as proper human-readable text instead of technical constants
3. Check that all currency entries show the updated rail names correctly
4. Ensure functionality remains unchanged - only display names should be different

### Why make this change?

Improves user experience by displaying payment methods with proper capitalization and spacing that users would recognize, rather than technical snake_case identifiers that are harder to read and understand.
