Extract shared helpers and fix strict-kwargs call sites

[adamtheturtle]

This refactor extracts shared VWS and CloudReco request/response helper logic into common modules to reduce duplication between sync and async clients. It updates the sync/async query, VWS, and VuMark service implementations to call the shared helpers. It also switches shared helper invocations to keyword arguments so the branch passes the project's mypy strict-kwargs checks. Pre-push checks (including mypy, pyright, pyrefly, and ty) passed during push.

Note

Medium Risk
Mostly a refactor, but it centralizes request signing/header construction and result-code→exception mapping; any mismatch could change how requests are authenticated or which errors are raised in both sync and async clients.

Overview
Refactors the sync/async VWS, CloudReco query, and VuMark clients to deduplicate request/response logic by introducing shared helpers (_vws_request.build_vws_request_args, _vws_common, _query_common) and routing existing code through them.

This centralizes VWS request signing + header/url construction, result-code→exception mapping for VWS/VuMark/CloudReco, and JSON body construction for add_target/update_target, while updating call sites to pass arguments via keywords (to satisfy strict kwargs type-checking) and making minor result parsing calls explicit via response_dict=.
