Remove unused get_progress_client function in learn-token contract

[DeFiVC]

What

The get_progress_client function in chainlearn-contracts/contracts/learn-token/src/lib.rs is defined but never called anywhere in the codebase.

Why

Dead code increases maintenance burden and can confuse developers about the codebase's actual dependencies.

Scope

Remove the unused function at lines 587-590.

Acceptance Criteria

• get_progress_client function is removed
• No other code references this function
• cargo test passes
• cargo build --release succeeds

Technical Context

• File: chainlearn-contracts/contracts/learn-token/src/lib.rs:587-590
• Function:

  fn get_progress_client(env: &Env) -> ProgressTrackerClient<'_> {
      let address = storage::get_progress_tracker(env);
      ProgressTrackerClient::new(env, &address)
  }

• Note: claim_reward uses env.invoke_contract directly instead of this function
