Stake Farming Feature on Wallet

[pretfood]

Problem

On stake farming contracts, users cannot see rewards in their wallet. At present, only $NEAR rewards are visible on the wallet. In new stake farming contracts, rewards are returned in $AURORA, but these are not visible.

Expected Behavior

Staking rewards should be displayed in more than one currency.

Steps to reproduce

1. Stake $NEAR tokens in aurora.pool.near
2. Watch how the rewards number never moves beyond 0, despite claimed APY of 29%.

There's work in progress, but no commitment on the timing for the release, as it needs a final review on the UX side.

@corwinharrell Would appreciate some design input on this. We created a first iteration on #2384 that impacts the main staking page to display NEAR token icons and the validator page to display NEAR balance with icon and other tokens if any e.g. the aurora validator:

Until we have a new UI, I think it is actually clearest to group the rewards under a single section and label. This way, it simply becomes a list of Rewards earned, and the icon and symbol denote the particular token, without the need for separate labels and sections.

I think the only remaining necessary change then would be to change the tooltip icon to read something like:

Rewards earned but not withdrawn. NEAR token rewards are compounding and are automatically re-staked.

UI and copy for v1 (token rewards display) updated in #2388
