1. kubectl credentials error (41 places in kube.rs)
Every kubectl invocation used .env("KUBERNETES_CONTEXT", context) which
is not a real kubectl environment variable — kubectl silently ignores it
and falls back to whatever current-context is set in the kubeconfig YAML.
If that context has expired or wrong credentials the auth failure occurs.
Replaced all 41 instances with .arg("--context").arg(context) so kubectl
always uses the correct context from the stored kubeconfig.
2. Cluster name still showed UUID (two causes)
a) Hotbar read from kubernetesStore.clusters (ClusterInfo[]) which is never
populated by the kubeconfig-based flow — always empty, so selectedCluster
was always undefined. Removed the Zustand cluster lookup from Hotbar and
added a clusterName prop passed from KubernetesPage.tsx (selectedConfig?.name).
b) ClusterOverview fell back to showing raw clusterId UUID when clusterName
was undefined. Changed subtitle to render conditionally so UUID never shows.
3. Bell dialog had no way to close
Custom DialogContent had no X button and no backdrop-click handler.
Added X close button (top-right) and backdrop-click-to-close.
4. Hotbar icons invisible in dark mode
variant="ghost" only styles hover state with no baseline text color.
Added className="text-foreground" to all icon-only ghost buttons.
Resolves four bugs in the Kubernetes management interface:
1. **Cluster not found error** - commands/kube.rs::list_nodes (and all other
kube resource commands) look up clusters from state.clusters (in-memory map)
which was never populated from the kubeconfig_files table. Add a new
connect_cluster_from_kubeconfig Tauri command that reads the encrypted
kubeconfig from the DB, decrypts it, and inserts a ClusterClient into
state.clusters. Wire it into KubernetesPage on initial load and cluster
change so the in-memory map is always populated before any kube command runs.
2. **Dropdown selection has no effect** - same root cause as #1; activating a
kubeconfig only updated the DB flag but never loaded the client into memory.
handleClusterChange now calls connectClusterFromKubeconfigCmd after activation.
3. **GUID shown instead of cluster name** - ClusterOverview displayed the raw
internal UUID as the page subtitle. Now accepts a clusterName prop (populated
from kubeconfig.context) and renders that instead. ClusterDetails similarly
changed to show kubeconfig.context in the header, not the UUID.
4. **Bell icon not clickable** - Hotbar bell button had no onClick handler. Add
optional onNotifications / notificationCount props; badge count is now dynamic
rather than hardcoded. KubernetesPage wires up a notifications dialog showing
active cluster context and a link to the Events section.
All changes follow TDD: failing tests written first, then implementation.
