Add a contract entrypoint to query a business's KYC verification status and rejection reason in one read

[Baskarayelu]

📋 Description

verification.rs exposes is_business_verified, get_verification, and bucket listers like get_rejected_businesses. A client wanting "is this business verified, and if rejected, why?" must call multiple functions and unpack the full BusinessVerification. This issue adds a compact get_business_kyc_status(business) -> (KycState, Option<String>).

Why this matters: the most common KYC query is "status + reason". A single compact read avoids deserializing the whole verification record and gives the UI a stable, minimal contract.

🎯 Requirements & Context

• Add get_business_kyc_status(env, business) -> Option<(KycState, Option<String>)> deriving from get_verification.
• Return None for businesses with no verification record.
• Reason is Some only when the state is rejected; otherwise None.
• Reuse existing state enum; do not duplicate it. Add /// docs.

Context & constraints

• SDK 25.1.1. Pure read; no auth.

🛠️ Suggested Execution

git checkout -b feature/business-kyc-status-query
cargo test -p quicklendx-contracts business_kyc_status -- --nocapture
cargo clippy -p quicklendx-contracts --all-targets -- -D warnings

• Edge cases: no record (None); verified (reason None); rejected (reason Some); pending.

I can take this one. I will add a read-only contract query that returns only the business KYC status plus rejection_reason, with regression coverage for missing, pending, rejected, verified, and resubmitted records. I will wait for assignment/confirmation before opening a PR.
