Add workflow_dispatch trigger to examples and tests workflows

[alex-clickhouse]

Lets us trigger tests manually

---

Note

Low Risk
Low risk CI-only change that adds manual triggers and parameterizes checkout ref; main risk is misconfiguring the ref input leading to running workflows against the wrong revision.

Overview
Adds workflow_dispatch support to examples.yml and tests.yml, enabling manual runs with an optional ref (branch/tag/SHA).

Threads this ref through the tests.yml job calls into reusable workflows (reusable.yml, tests-integration.yml, tests-cloud.yml, tests-windows.yml, tests-macos.yml) and updates checkout steps to use ${{ inputs.ref || github.ref }} so workflows can run against a specified revision.
