Desktop: Re-render note when resources are changed

[personalizedrefrigerator]

Summary

This pull request causes notes to be re-rendered when resources change. This is intended specifically to show changes to resources through the plugin/data API, but also applies to other changes made with Resource.save.

Notes

• Previously, notes would re-render when resources changed, but only in certain cases: when watched by the ResourceEditWatcher, when finished downloading/decrypting, and when download starts. This did not handle the case where a resource is updated through the data API.
• This allows removing an only-partially-working workaround in the Freehand Drawing plugin.
• This may be important for Desktop: File system mirroring #10448 when resource mirroring is implemented.

Testing plan

In addition to this pull request's automated test, this can be tested by:

1. Installing the Freehand Drawing plugin (if not already installed)
2. Adding a new drawing
3. Selecting the drawing's resource ID
4. Opening the command palette and running :insertDrawing__newWindow
   • Prior to this pull request, changes made in a new window were not reflected in the note viewer without switching notes.
5. Making a change to the drawing
6. Clicking "save"
7. Verifying that the drawing updates

This has been tested successfully on Ubuntu 24.04.

This pull request also causes ResourceChange events to be emitted when a resource's metadata changes. Previously, ResourceChange events were fired only while resources were being watched.
