feat(cos): rename per-app overrides to per-app options and clarify the enable toggle

[atomantic]

Summary

The per-app section of a scheduled task was called "Per-app overrides", which made its toggle read like an "apply my overrides" flag. It is not — it is the switch that decides whether the task runs for that app at all, and every other control on the row is inert until it is on.

This renames the surface and makes the toggle say what it does.

Per-app options (CoS → Schedule / Workflow)

• "Per-app overrides" → "Per-app options" across the task drawer tab, the PerAppOverrideList heading, the Workflow timeline expander + panel label, and the app-tasks section blurb.
  • The drawer tab id stays overrides, so existing ?taskTab=overrides deep links keep resolving — only the label changed.
• Each row's switch now carries a visible "Enabled" label plus an accessible name and tooltip naming the task, the app, and the current state (feature-ideas enabled for Acme: off → "feature-ideas does not run for Acme. Turn on to schedule it for this app."). It previously read Enable feature-ideas for Acme, with no visible label at all.
• The section subtitle now states the rule outright: an app stays off until you switch it on here, and everything else is optional (Inherit follows the global defaults).
• Bulk button widened from Enable All → Enable for all apps, with a tooltip.

Edit App → Automation

Same data, viewed per task, so it gets the same treatment:

• "Task Type Overrides" → "Scheduled Task Options", with a subtitle explaining the toggle.
• The per-task switch — which previously had no accessible name whatsoever — gains the Enabled label, an accessible name, and a tooltip.
• Labelled Enabled rather than Run, deliberately: that row already has a Run (trigger-now) button, and two controls under one word with opposite meanings is worse than the ambiguity being fixed. A comment at the site records why.

No behavior, data-shape, or API change — the persisted appOverrides / taskTypeOverrides keys are untouched on the wire.

Test plan

• New AppOverrideRow — enabled toggle tests pin the accessible name across both the mobile and desktop render slots (asserted per-slot via getAllByRole, not by index) and verify the toggle enables the task while preserving the app's interval override.
• Existing TaskConfigDrawer, WorkflowTab, and AutomationTab tests updated to the new labels.
• npm run lint clean; full client suite green — 10210 passed, 2 skipped, 834 files.
