refactor: move CardNetwork type from transactions to commons

The `CardNetwork` enum has been relocated from
`src/api/resources/transactions/types/` to
`src/api/resources/commons/types/` and is now re-exported from the
commons index. The transactions index no longer exports it directly.

Key changes:
- Moved `CardNetwork` definition to `commons/types/CardNetwork.ts`
- Added `CardNetwork` export to `commons/types/index.ts`
- Removed `CardNetwork` re-export from `transactions/types/index.ts`
- Added JSDoc comment describing supported card networks
