Fix: Intake open count not updating after accept, decline, or duplicate

[a-faqahmad]

This pull request updates the inbox issue actions in inbox-issue-header.tsx to ensure that the inbox issue list is always refreshed after key actions (accept, decline, duplicate). This helps keep the UI in sync with the latest data after any status changes.

Inbox issue list refresh improvements:

• The fetchInboxIssues function from useProjectInbox is now imported and used to refresh the issue list after accepting, declining, or marking an issue as duplicate.
• After accepting, declining, or marking an issue as duplicate, fetchInboxIssues is called to reload the inbox issues, ensuring the UI reflects the latest state. [1] [2]

Fixes #8473

---

[!NOTE] Ensures the intake inbox stays in sync after key actions.

• Import and invoke fetchInboxIssues from useProjectInbox after accept, decline, and mark as duplicate actions in inbox-issue-header.tsx to refresh the list (with "filter-loading"), wrapped in try/catch with console logging
• No changes to snooze/delete flows or navigation
