feat(standups): Auto-open response discussion based on query param

[jmtaber129]

Description

If a responseId query param is present when the Team Prompt Meeting is initially rendered, try to find the corresponding response card, and open its discussion.

Update the in-app and email notifications for standup mentions to include this query param.

In the future, we could use this to enable share-ability by either adding "copy link" buttons to response cards and/or keeping the query param in-sync with open discussion drawers.

Marking this as one review required because this general pattern has already been approved by maintainers in #7225

Demo

In-app - https://www.loom.com/share/45eb8249c162428faceb75f42f6351c6
From email link - https://www.loom.com/share/399f00c8e8a047c4819411ca4d69f85d

Testing scenarios

• Trigger a standup mention notification from user B to user A
• Send notification email batch
• Click the "see their response" link in user A's email, and confirm it auto-opens user B's response
• Click the "see their response" link in user A's notifications dropdown, and confirm it auto-opens user B's response

Final checklist

• I checked the code review guidelines
• I have added Metrics Representative as reviewer(s) if my PR invovles metrics/data/analytics related changes
• I have performed a self-review of my code, the same way I'd do it for any other team member
• I have tested all cases I listed in the testing scenarios and I haven't found any issues or regressions
• Whenever I took a non-obvious choice I added a comment explaining why I did it this way
• I added the label One Review Required if the PR introduces only minor changes, does not contain any architectural changes or does not introduce any new patterns and I think one review is sufficient'
• PR title is human readable and could be used in changelog
