Fix blank task-detail modal for Google Tasks

loadTaskDetailData/HandleUpdateTask only had cases for "trello" and
"doot" sources, so opening a gtask from the Tasks or Timeline tab
rendered an empty title/description. Reuses the existing
findGoogleTask cache lookup for both. Renamed the API client's
UpdateTaskNotes to UpdateTask(title, notes) so the web modal can save
an edited title too, not just description; the widget's
description-only edit popup now just round-trips the task's existing
title unchanged.
