Fix post-create redirect and add bracket filter to jobs list

- After job creation always redirect to /jobs (never bracket detail)
- If a bracket was involved, redirect to /jobs?bracket_id=X instead
- GET /jobs?bracket_id=X filters the list and shows a dismissible bracket badge
- Amount label now says '(≥2 creates a bracket)' to make the side effect clear
