Consider manual runs when determining next run input

[taylordowns2000]

Description

This PR closes #4584 .

Cron-triggered workflow runs were ignoring manual run outputs when determining the next input state.

last_run_final_dataclip/1 filtered by wo.trigger_id, which excluded manual runs (whose work orders have trigger_id = nil).

Changed the filter to scope by wo.workflow_id instead, so the most recent successful run is used regardless of how it was triggered. While you could argue that we shouldn't consider manual runs when calculating the next input state for a scheduled run, this isn't how we do it when using the "single step" option, so we should keep it the same for "Final run state" option.

Validation steps

1. Create a workflow with a cron trigger and at least one job
2. Run the workflow via the cron trigger (or wait for it to fire) — confirm it succeeds
3. Manually run the same workflow using "Empty input" — confirm it succeeds
4. Wait for (or trigger) the next cron execution
5. Verify the new cron run's input dataclip is the final_dataclip from the manual run (step 3), not the older cron run (step 2)

Additional notes for the reviewer

1. The cron_cursor_job_id path (last_successful_step_dataclip/1) was already unscoped by trigger and did not have this bug — only the cron_cursor_job_id = nil path was affected.
2. Two new test cases added in invocation_test.exs: one for manual runs being picked up, one for recency ordering across trigger types.
