Split init into separate queries and simplify tasks panel

- Replace InitResponse with separate getTasks and getTemplates queries
  with independent poll intervals (10s tasks, 5min templates)
- Remove extension-side template cache in favor of React Query staleTime
- Add resume button to TaskMessageInput for paused tasks
- Reject message sends to paused tasks instead of auto-starting workspace
- Extract TasksPanel component and usePersistedState hook from App
- Centralize query keys in config.ts
- Rename TasksPanel to TasksPanelProvider on the extension side
- Add refresh bar indicator for initial load and user-triggered refresh
