Support wheel dispatch from existing release tags

[dkirov-dd]

Summary

• add a backward-compatible create-tags input to the shared wheel release workflow, defaulting to true
• support a no-tag mode that detects packages from release tags already pointing at the requested source ref
• fail closed when automatic no-tag detection finds no releasable packages
• preserve explicit-package recovery and the existing integrations-core tag-creation behavior

Why

Legacy GitLab must remain the sole release-tag creator for integrations-extras and marketplace. Those repositories will dispatch this reusable workflow only after signing and pushing tags at the exact source SHA.

Verification

• PYTEST_DISABLE_PLUGIN_AUTOLOAD=1 python -m pytest tests/ -q — 134 passed
• python -m compileall -q .
• git diff --check
• actionlint: only the same two pre-existing SC2086 findings present on origin/master; no new workflow finding

Rollout

Merge this PR before enabling either source-repository handoff. Existing callers are unchanged because create-tags defaults to true.
