Modeling view appearance final tweaks (#6425)

* Remove bug button from LowerRightControls

There is a "report a bug" button in the help menus, both native and
lower-right corner. This is overkill, and users are not using coredump
well.

* Remove coredump from refresh UI button

* Add a "Refresh app" command to palette

* Update snapshots

* Rework "Refresh and report bug" menu item to "Report a bug"

* Add refresh button to sidebar

* Convert upper-right refresh button to Share

* Tweak styles of command button

* Make anonymous user icon same size as known user image

* Remove ModelStateIndicator

* Use hotkeyDisplay for the sidebar too

* Update snapshots

* Remove tooltip from command bar open button

* tsc, lint, and fmt
