handle non-transferable currency (#1894)

* feat: Add nonTransferable field to Currency type and validator schema

Support non-transferable currencies (e.g., Akash ACT token) by adding
an optional nonTransferable boolean to the Currency interface and
corresponding Joi validation in chain-validator.

* feat: Hide non-transferable currencies from send/swap UI

- Token detail: disable Send, Receive, Swap buttons for nonTransferable
- Send asset selection: filter out nonTransferable tokens
- Swap destination: filter out nonTransferable tokens from owned list

* feat: Add nonTransferable property to Currency interface

- Introduced an optional nonTransferable boolean field to the Currency interface, indicating whether a currency can be transferred on-chain. This enhances the currency type definition to support non-transferable assets.
