refactor: show tasks instead of projects in sidebar

The left sidebar now lists individual tasks (sorted by creation time)
instead of project cards. Each task shows the task title prominently
with the project name as subtitle, along with step progress and
session status. Selecting a task shows its step timeline in the
center panel.
