chore(deps): update web3 requirement from >=7.15.0 to >=7.16.0 in /bal_tools

[dependabot]

Updates the requirements on web3 to permit the latest version.

Changelog

Sourced from web3's changelog.

web3.py v7.16.0 (2026-05-01)

Bugfixes

- Fixed ``ens.utils.is_none_or_zero_address`` not detecting bytes-form zero addresses (``b"\x00" * 20``) — the function compared against the hex string ``EMPTY_ADDR_HEX`` only, even though its signature accepts ``Address`` (which is ``bytes``). This caused ``ens.address(name, coin_type=N)`` to return the zero-address checksum string instead of ``None`` when the resolver recorded a zero address. (`[#3830](https://github.com/ethereum/web3.py/issues/3830) <https://github.com/ethereum/web3.py/issues/3830>`__)
Features

• ENS read operations now use the Universal Resolver (0xeEeEEEeE14D718C2B47D9923Deab1335E144EeEe) instead of querying the ENS Registry directly, aligning with ENSv2 readiness requirements. ([#3830](https://github.com/ethereum/web3.py/issues/3830) <https://github.com/ethereum/web3.py/issues/3830>__)

Bugfixes

• Fix HTTPProvider to share an explicitly provided session across all threads, rather than only the creating thread. ([#3800](https://github.com/ethereum/web3.py/issues/3800) <https://github.com/ethereum/web3.py/issues/3800>__)
• Fix TypedDict field names to use camelCase (validatorIndex, yParity) matching JSON-RPC conventions and formatter outputs. ([#3801](https://github.com/ethereum/web3.py/issues/3801) <https://github.com/ethereum/web3.py/issues/3801>__)
• Exclude type checking in Sphinx module and submodules ([#3803](https://github.com/ethereum/web3.py/issues/3803) <https://github.com/ethereum/web3.py/issues/3803>__)
