Task manager: 3-column grid layout + tasks-over-time bar chart

[Copilot]

The task manager overview had poor horizontal space utilization (single-column list) and no time-series visualization for task outcomes.

Backend

• New Task.getTasksOverTime action — MongoDB aggregation that buckets succeeded/failed/cancelled tasks by scheduledAt into configurable time windows (bucketSizeMs). Returns [{ timestamp, succeeded, failed, cancelled }] sorted ascending.

Frontend

• "Tasks Over Time" stacked bar chart (Chart.js, dark-mode aware) inserted between the summary cards and the task list. Bucket granularity is auto-selected by date range:

  Range	Bucket
  Last hour	5 min
  Today / Yesterday	1 hour
  This week / Last week / Month	1 day

• "Tasks by Name" grid — replaced single-column <ul> with a responsive CSS grid (md:grid-cols-2 xl:grid-cols-3). Each card retains all 4 status buttons (Pending, Succeeded, Failed, Cancelled).
• getTasks() now fetches overview + time series in parallel via Promise.all.

API client

• Added getTasksOverTime to both the Lambda and Express API client variants.

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• fastdl.mongodb.org

  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node node ./node_modules/.bin/mocha test/ChatThread.share.test.js test/Dashboard.evaluate.objectid.test.js test/Dashboard.getDashboard.error.test.js test/Dashboard.updateDashboard.test.js test/Model.deleteDocuments.test.js test/Model.getDocuments.filter.test.js test/Model.getDocuments.sort.test.js test/Model.streamDocumentChanges.test.js test/Model.updateDocument.test.js test/Task.getTaskOverview.test.js test/Task.getTasks.test.js test/Task.getTasksOverTime.test.js test/document-search-autocomplete.test.js test/helpers.getModelDescriptions.test.js test/setup.test.js test/util.deepEqual.test.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

This section details on the original issue you should resolve

<issue_title>Task manager grid layout and chart over time</issue_title>
<issue_description>Currently the task manager doesn't make good use of available horizontal space, very low information density. Let's see if we can fit 2 or 3 "tasks by name" cards per row.

Also, let's add a bar chart showing tasks succeeded/failed/cancelled over time within the selected window broken up into reasonable buckets. For last hour, likely broken up into 5 minute buckets would be great. For last day, show per hour, etc.</issue_description>

<agent_instructions>When creating the groups of 3 tasks by name, each individual task should have the 4 status options as part of it.</agent_instructions>
