Add SDK `getInsurancePoolInfo` method

[Levi-Ojukwu]

Description:

The insurance pool contract exposes four view functions that the SDK does not wrap:

• get_pool_balance(env) → i128 — current pool balance
• get_coverage(env) → i128 — configured coverage cap
• is_enrolled(env, lp) → bool — LP enrollment status
• get_premiums_paid(env, lp) → i128 — total premiums paid by an LP

Why it matters: Frontend applications need to display insurance pool status and LP enrollment.

Acceptance Criteria:

• Create methods for each view function
• Add TypeScript types for insurance pool data
• Add tests

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

Hi! I'd like to work on this issue.

I have experience working with TypeScript SDKs, blockchain integrations, and writing well-tested API wrappers. For this task, I'll add typed SDK methods for all four insurance pool view functions (get_pool_balance, get_coverage, is_enrolled, and get_premiums_paid), introduce the appropriate TypeScript types, and add comprehensive tests to verify the SDK behavior.

I'll review the existing SDK patterns to ensure the new methods follow the project's conventions, keep the implementation clean and maintainable, and ensure the new functionality integrates seamlessly with the existing API surface before submitting a PR.
