Introduce managed secrets owned by GitOps that can be defined once and
pushed to any combination of projects/groups across connections. Values
are stored in OS keychain, secrets appear on targets as GITOPS_{key}.
Projects "View Secrets"/"View Pipelines" and Groups "View Secrets" now
pass connection/scope/entity context so the target view opens with
filters pre-filled. Fixed double-load bug where dees-simple-appdash's
view-select event re-dispatched setActiveViewAction without context.
- Add Edit and Pause/Resume actions to connections table
- Add delete confirmation modal to secrets table
- Add 'paused' status to connections with full backend support
- Skip paused connections in health checks and secrets scanning
- Add global ActionLog service with filesystem persistence
- Instrument all mutation handlers (connections, secrets, pipelines) with action logging
- Add Action Log view with entity type filtering to dashboard
