feat(caddy): route edit, system log entries, fix routes load timing

Add inline edit for custom routes (Pencil icon → inline form with all fields).
Log route add/update/delete/import to the logs table (type: system) so
operations appear in the Logbook. Fix loadCaddyRoutes() called without await
after settings save, causing a race between the success message and route list.
