navigator window issues

Issue type

UX/Interaction bug (incorrect behaviour)

Description with steps to reproduce

Here are 3 issues I have found while using the navigator.

First issue:

1. range select a measure
2. double click on the navigator score.
3. result: opens input mode.

Second issue:

1. click anywhere in the empty space of the navigator window
2. result: navigates to the corresponding edge -- accidental clicks become very annoying. Only clicks inside the navigator score should be allowed.

Thisrd Issue:

1. Naviagator score bounds dont update correctly after changing score height by adding/removing instruments or when changing view mode - need to manually resize the navigator window to update. (sometimes even that doesnt get the score to snap to the left side)

Reproduce the three navigator behaviors described in the issue using MuseScore Studio 4.7 on Windows 11, with the attached videos as reference. Trace the navigator's click handling and score-bound updates; done means double-clicking and empty-space clicks no longer trigger unintended actions, and bounds follow score or view-mode changes without manual resizing.
