Wire bbot_io_api_key config through to asndb

[liquidsec]

Fixes #3108

Summary

• Adds a top-level bbot_io_api_key config field (mirrors interactsh_token) that flows through ASNHelper to the asndb library.
• Previously the only way to set this credential was the BBOT_IO_API_KEY env var (read by the asndb library directly), with no BBOT-side config slot, no preset visibility, and no way to put it in secrets.yml.
• Env var still takes precedence (asndb's own os.getenv(...) or kwarg behavior).

This might be because:

• Benchmarks failed to run
• No benchmark tests found
• Dependencies missing

CI failure here is unrelated to this PR — it's the wpscan/Ruby breakage affecting all current PRs. wpscan 4.0.0 shipped 2026-05-19 and requires Ruby >= 3.3, but the GHA runners have Ruby 3.2.3, so test_cli_args's --install-all-deps assertion fails for every PR.

Fix is in #3111 (pins wpscan to 3.8.28). Once that lands I'll rebase this PR and CI should go green.
