fix: event start behavior from the pipeline jobs view

[yk634]

Context

In the pipeline jobs job list view, the start action was using the SHA from the latest pipeline event instead of the repository's latest commit.

This area had also become harder to follow because the same confirm-action flow is used from both pipeline/jobs and pipeline/workflow, and the branching logic had grown to cover multiple cases in one place.

In addition, the jobs view modal state was not being reset correctly. After opening the restart modal and closing it, a subsequent start action could incorrectly reuse restart-related event data.

Objective

Update the pipeline jobs job list view so that the start action uses the repository's latest commit instead of the latest pipeline event SHA.

This PR also:

• refactors the confirm-action branching to make the different jobs view and workflow cases clearer
• fixes stale modal state in the jobs view so restart event data is not carried into a later start action
