feat: add a compact job list view to the Jobs tab

Each job can now render as a single line — name on the left, status on the
right — instead of the three-line block, so many more jobs fit without
scrolling. A toggle button beside the Folder filter switches between the two
modes and is labelled with the action it performs, matching the existing
"Disable auto" convention.

The choice is persisted as Config.JobListView ("detailed" / "compact", stored
as job_list_view in gosentry.json). Empty, legacy, and unrecognised values all
normalize to detailed, so existing installs keep the current look and the file
never gains a value no reader understands.

Selection, the details panel, the folder filter, and live status updates work
unchanged in both modes.

 ## Unreleased
 
+**Compact job list view.**
+
+- The Jobs sidebar can now render each job as a single line — name on the left,
+  status on the right — instead of the three-line block. A toggle button beside
+  the Folder filter switches between **Compact** and **Detailed**; it is
+  labelled with the action it performs, like the "Disable auto" button. Compact
+  fits many more jobs on screen without scrolling; selection, the details panel,
+  the folder filter, and live status updates all work unchanged in both modes.
+- The choice is persisted as a new `Config.JobListView` field
+  (`"detailed"` / `"compact"`, written to `gosentry.json` as `job_list_view`),
+  so it survives a restart. Empty/legacy configs and any unrecognised value
+  normalize to detailed, so existing installs keep the current look.
+
 **Timeouts: 0 now means "no timeout" at both levels.**
 
 - The global **Default timeout** in Settings now defaults to `0`, meaning jobs
