Support setting reward permission for nomination pool

[nampc1]

To improve UX, we should allow users to choose whether to compound their rewards automatically or to manually claim them

Logic:

• [x] Batch claim permission with joinPool extrinsic
• [x] Support claim permission extrinsic as a standalone function

UI:

• [x] Add claim permission option to stake screen
• [x] Add new button for claim permission
