chore: adds non-evm staking

[zone-live]

Explanation

Adds a generic non_evm_staking state structure to support staking APY data for non-EVM chains (starting with Tron).

Tron staking uses a different approach than EVM pooled staking, so rather than forcing Tron into the existing pooled_staking structure (which would require nullable vault-specific fields and some conditional logic), this introduces a minimal state that can accommodate any non-EVM chain.

The idea next is for the mobile client to:
1 - Call EarnController.refreshNonEvmStakingApy() with Tron witness API fetcher
2 - Use the selectors in selectEarnTokens to populate earnToken.experience.apr with the Tron APY
3- Get rid of the useTronStakeApy hook calls from components

Note

Add generic non-EVM staking state with APY refresh/getter, expose selectors/exports, and update tests and selector typings.

• EarnController:
  • Add generic non_evm_staking state/types and metadata; initialize with {}.
  • New methods: refreshNonEvmStakingApy({ chainId, apyFetcher }) and getNonEvmStakingApy(chainId).
• Selectors:
  • Add selectNonEvmStaking, selectNonEvmStakingForChainId, selectNonEvmStakingApyForChainId.
  • Tighten return typings for several existing lending selectors.
• Exports:
  • Export new non-EVM staking types, defaults, and selectors via index.ts.
• Tests:
  • Add tests for non-EVM staking methods and selectors; update state derivation snapshots to include non_evm_staking.
