Add SDK reputation bonus `getConfig` and `getReputation` methods

[Levi-Ojukwu]

Description:

The reputation_bonus contract has two view functions not exposed by the SDK:

• get_config(env) → Config — returns high_rep_threshold, bonus_bps, min_discount_rate_bps
• get_reputation(env, address) → ReputationScore — returns invoices_submitted, invoices_paid, invoices_defaulted, score

Why it matters: Frontend applications need to display reputation configuration and participant scores.

Acceptance Criteria:

• Create getReputationBonusConfig() returning Config
• Create getReputationBonusReputation(address) returning ReputationScore
• Add TypeScript types
• Add tests

Relevant Files: contracts/reputation_bonus/src/lib.rs, sdk/src/index.ts

I have experience with TypeScript and SDK development and have reviewed the issue description. My approach will be to inspect the existing contract view functions, expose them through the SDK using the project's existing patterns, add the corresponding TypeScript types for Config and ReputationScore, and include tests to verify the new methods work as expected. I can submit a well-tested PR that follows the project's conventions.
