v0.9.12

• Prevented Update Manager inventory rendering from falling back to live registry lookups when sampler cache details are missing, which keeps the modal responsive on slow or unreachable registries.
• Reused the already-built update candidate inventory for the auto-update tab so ready targets still appear there even when they do not currently have a pending update.
• Added a 15 second timeout to Update Manager fetches in the dashboard and surface a clearer error when Docker or registry metadata takes too long to respond.
