Fix e2e claim token API test draining calibnet test wallet

[sudo-shashank]

We’ve encountered an issue with the new end-to-end (e2e) claim token API test. The test sends tokens to another wallet address but does not recover them at the end of execution. As a result, after some test runs, the calibnet tFIL test wallet gets drained, leading to failing tests once its balance is depleted.

Steps to Reproduce:

• Run the new claim token API e2e test multiple times on calibnet.
• Observe that the test wallet balance continuously decreases.
• Eventually, tests start failing due to insufficient funds.

Expected Behavior:
The test should recover tokens back to the originating test wallet after completion, ensuring balance consistency across runs.

Proposed Fix:

• Update the claim token API e2e test to return tokens to the original test wallet after execution.
• Recover any tokens currently sitting in the receiving test wallet.
• We may be able to use FilForwarder to recovery the tokens easily

Additional Context:

The issue is only observed for calibnet tFIL claim token api e2e test.
The tokens are not lost or burned — they’re being transferred to another internal test wallet owned by us.
