feat: add trusted search to user lookup methods

[IldarDM]

Summary

• Add trusts_search and partial_response options to user search by HUID, AD login, and other ID.
• Forward enabled options as query parameters to the corresponding BotX API endpoints.
• Preserve the existing request shape when both options use their default values.
• Document trusted search in the user lookup example.

The BotX API exposes these options consistently for all user search endpoints:

PR checklist

• I've written good commit message for all commits
• I've split changes into separate commits where it's appropriate
• I've added the description of function to documentation
• I've updated project version in pyproject.toml
• I'll make a release when PR is merged
• I'll bump pybotx in bot-template

The release and bot-template updates require maintainer access and are intentionally left for the project maintainers.
