chore: adds non-evm staking

[zone-live]

Explanation

Adds a tron_staking state structure to support staking APY data for 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 conditional logic), this introduces a dedicated Tron specific state.

We opted for a chain-specific key (tron_staking) rather than a generic non_evm_staking map because different non-EVM chains may have significantly different data requirements. This approach is more explicit and if we add other non-EVM chains later, they can have their own state structures.

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

Adds TRON staking APY support to EarnController with a new tron_staking state, fetch/update method, selectors, exports, and tests.

• Earn Controller:
  • State: Introduces tron_staking (TronStakingState) with metadata; defaults to null (DEFAULT_TRON_STAKING_STATE) and included in getDefaultEarnControllerState.
  • Methods: Adds refreshTronStakingApy(apyFetcher) and getTronStakingApy().
  • Exports: Exposes TronStakingState, DEFAULT_TRON_STAKING_STATE, and new selectors via src/index.ts.
• Selectors:
  • Adds selectTronStaking and selectTronStakingApy.
  • Tightens return types on existing lending selectors.
• Tests:
  • Adds tests for TRON staking state/methods/selectors and updates metadata snapshots.
• Docs:
  • Updates CHANGELOG.md to note TRON staking APY support.
