Fix major Nearlight deviations from design review

- Expose End conversation + readable draft during connecting/waiting
- Stop masking assistant speaking/thinking state in Type/muted modes
- Restrict failure diagnosis to real causes (no invented network text)
- Replace old blue tint with Rosewood everywhere
- Fix transcript short-content bottom-anchor (top-align short histories)
- Settings: visible Server URL label, focus on rejected save, edit clears
  saved confirmation, trim-aware unchanged detection
- Task detail: live store lookup with missing-task state
- Task rows: status text label restored
