Add SDK `getDistributionAccrual` method

[Levi-Ojukwu]

Description:

The distribution contract exposes get_accrual(participant) (at lib.rs:98-100) that returns the total tokens earned by a participant. The SDK does not expose this method.

The accrual is calculated from three sources:

• LP funding volume reward: lp_volume / 100_000_000 * 10_000_000
• Freelancer settlement reward: freelancer_settled * 5_000_000
• Payer on-time reward: payer_on_time * 5_000_000

Why it matters: Participants need to see their pending token earnings before claiming.

Acceptance Criteria:

• Create a function that calls the contract's get_accrual view
• Return the total earned amount as a number
• Add tests
