tests: add comprehensive tests for Token-2022

[Shubbu03]

Add integration tests for Token‑2022 support and document current metadata limitations.

• Token‑2022 lifecycle: create mint, initialize, create ATAs, mint, transfer, burn, and close accounts (test_token2022_full_lifecycle).
• Error handling: transferring/burning more than balance and closing accounts with non‑zero balance (test_token2022_error_cases).
• Delegation: approve delegate, delegated transfer, revoke, and ensure post‑revoke transfers fail (test_token2022_delegate_operations).
• Freeze/thaw: freeze accounts, verify transfers fail while frozen, thaw, and confirm transfers succeed afterward (test_token2022_freeze_thaw).

completes requested tests by @lgalabru in #431

also i tried the InvalidRealloc issue around Token‑2022 metadata init. I added an integration test that tries to replicate the spl-token CLI flow, but in our Surfpool/LiteSVM environment the metadata instruction currently fails earlier with “incorrect program id for instruction" rather than InvalidRealloc so currently stuck there

Very nice, thanks @Shubbu03!

Thanks @Shubbu03! Could you rebase your branch with main? That flaky test should be fixed now.
