[ZEPPELIN-6351] Close modals only on their own user actions

### What is this PR for?
On the home page, an open modal (e.g., `Import Note`, `Create New Note`) closes when a  `NOTES_INFO` message is received.

This is unexpected and makes running parallel E2E tests that create new notes unreliable.

#### Root cause
Both modals treated any `NOTES_INFO` message as the result of *their* own submit action.
Since `NOTES_INFO` message is broadcast for various events, this led to false positives.

#### Fix
Close modals only in response to messages addressed to the submitting client: `IMPORT_NOTE` and `NEW_NOTE`. The server already sends `NEW_NOTE` (used by the old UI), but not `IMPORT_NOTE`. I added a server-sent `IMPORT_NOTE` and replaced `broadcastNote(note)` with sending `IMPORT_NOTE` only to the caller. The previously broadcast `NOTE` is mainly useful to users already on that note page; for a newly imported note, no user is on that page yet, so the broadcast is unnecessary.

### What type of PR is it?
Bug Fix

### What is the Jira issue?
[[ZEPPELIN-6351]](https://issues.apache.org/jira/browse/ZEPPELIN-6351)

### How should this be tested?
- Open two browser windows (A and B).
- In A, open a modal (e.g., Import Note or Create New Note).
- In B, perform a submit that triggers a note update. Verify the modal in A does not close.
- In A, submit the modal. Verify it closes and the note list updates.
