Summary

• Pre-authorizes the DeFindex vault's nested token movements in both adapter directions with env.authorize_as_current_contract.
• Deposit authorizes the vault's usdc.transfer(adapter, dfx, amount) pull.
• Withdraw authorizes the DeFindex vault's withdraw burn of the adapter's dfTokens.
• Adds deposit and withdraw auth-tree tests that run without mock_all_auths_allowing_non_root_auth.

This fixes the deposit path only. #1128 also requires the withdraw burn path to register the nested token authorization, with a test that exercises it. Please add the withdraw fix and a withdraw auth-tree test. The Soroban job also fails on cargo fmt --check, so run cargo fmt --all.

This covers deposit. The withdraw path at lib.rs:243 still calls DeFindex's withdraw without the equivalent nested authorization, and no withdraw auth-tree test exercises it.

@ibochivincent-lang thank you for the update. The withdraw authorization and auth-tree coverage are in place and all required checks pass. Please consider picking up another open issue.
