Replace index with id in actions routes (#36842)

This PR migrates the web Actions run/job routes from index-based
`runIndex` or `jobIndex` to database IDs.

**⚠️ BREAKING ⚠️**: Existing saved links/bookmarks that use the old
index-based URLs will no longer resolve after this change.

Improvements of this change:
- Previously, `jobIndex` depended on list order, making it hard to
locate a specific job. Using `jobID` provides stable addressing.
- Web routes now align with API, which already use IDs.
- Behavior is closer to GitHub, which exposes run/job IDs in URLs.
- Provides a cleaner base for future features without relying on list
order.
- #36388 this PR improves the support for reusable workflows. If a job
uses a reusable workflow, it may contain multiple child jobs, which
makes relying on job index to locate a job much more complicated
