feat(workflow): align history propagation API with go-sdk

[nelson-parente]

Summary

Aligns the workflow history propagation surface added in #1025 with the freshly-renamed go-sdk helpers (durabletask-go#105, merged 2026-05-19). That rename landed four days after #1025 merged, so this is drift, not a defect — Cassie flagged it post-merge while building the cross-SDK quickstarts.

This brings python-sdk back in line for cross-SDK parity before 1.18 ships.

Read API renames

Mirror durabletask-go's GetLast*ByName form to make it obvious these return the most-recent occurrence (with plural get_*s_by_name siblings for the full list):

Old	New
PropagatedHistory.get_workflow_by_name	get_last_workflow_by_name
WorkflowResult.get_activity_by_name	get_last_activity_by_name
WorkflowResult.get_child_workflow_by_name	get_last_child_workflow_by_name

Plural variants (get_workflows_by_name, get_activities_by_name, get_child_workflows_by_name) and chain-level helpers (get_app_ids, get_events_by_*) are unchanged.

Scheduling helpers

Add factory helpers mirroring workflow.PropagateLineage() / workflow.PropagateOwnHistory() from go-sdk:

import dapr.ext.workflow as wf

yield ctx.call_child_workflow(
    process_payment,
    input=req,
    propagation=wf.propagate_own_history(),
)

yield ctx.call_activity(
    log_summary,
    input=None,
    propagation=wf.propagate_lineage(),
)

The PropagationScope enum is kept as the underlying value, so propagation=PropagationScope.LINEAGE and propagation=propagate_lineage() are both supported.

Non-goals

• Kwarg name unchanged (propagation=). Renaming to with_history_propagation= would mirror go-sdk's WithHistoryPropagation() more literally but isn't idiomatic Python; happy to follow up if reviewers prefer it.
• No proto / runtime changes. This PR is purely surface-level: factory funcs return enum values; renamed methods are direct renames.

Test plan

• uv run ruff check --fix && uv run ruff format — clean
• uv run pytest ext/dapr-ext-workflow/tests/durabletask/test_propagation.py ext/dapr-ext-workflow/tests/durabletask/test_propagation_wiring.py — 31 passed
• uv run python -m unittest discover -v ./ext/dapr-ext-workflow/tests — 133 passed
• uv run pytest tests/examples/test_workflow.py::test_history_propagation against a 1.18-RC sidecar (output-based test; print statements unchanged, should still pass)
• CI green
