feat(ui): complete Batch 2 — LiveText display, start feedback, modal theming, ListEditor config

- Replace LiveLines with formatted LiveText + StreamLineFormatter
- Add log reload from disk for completed tasks
- Add start feedback (starting.../running) on detail and list views
- Apply dark theme (WindowBgBrush, AccentBrush) to editor modals
- Add model/system-prompt/agent-path config to ListEditorView
- Wire config loading/saving in MainWindowViewModel
- Fix duplicate AgentInfo DTO (use canonical Data.Models version)
