Refactor: Simplify case status display

Introduce a `Badge` enum and a `badge_for` function to consolidate
case status logic. This replaces multiple boolean flags (`analyzing`,
`has_failed_recording`, `analysis_required`) with a single, more
expressive `badge` field.

The HTML template has been updated to use this new badge system,
removing old status classes and logic. The `scan_user_cases` function
no longer needs the `worker_busy` argument as the analysis state is
now derived directly from the `auto_trigger` state.

This change improves code clarity and maintainability by centralizing
status determination and reducing redundant boolean flags.
