Fix public email override task links

[cursor]

Changes

• Bypass grouped-email buffering when a task notification includes a public API email override.
• Preserve the individual task email payload, including ctaParams.taskId, for overridden evaluation/task emails.
• Update the public email override docs to reflect immediate individual delivery for override emails.

Testing Criteria

• yarn test src/app/api/notification/notification.service.test.ts --runInBand — verifies override emails bypass grouping for single and bulk/company-recipient paths while retaining task CTA params.
• yarn lint:check — passes with existing React hook warnings only.
• yarn prettier:check "docs/PUBLIC_TASK_EMAIL_OVERRIDE.md" "src/app/api/notification/notification.service.ts" "src/app/api/notification/notification.service.test.ts" — passes.
• yarn tsc — blocked by pre-existing src/icons/index.ts SVG module declaration errors unrelated to this change.

Notes

• Linear MCP returned 401 and Sentry MCP required auth, so I could not directly fetch Sentry event metadata or post the required Linear comment from the automation.

Impact & Surface Area of Change

• Public API-created task assignment emails with custom override copy now send as individual emails instead of being collapsed into the 5-minute grouped-email summary.
• Default/non-overridden client assignment/shared/comment emails continue to use the grouped-email buffer.
