Local Dev 3dbbc452cd fix(theseus): an installed app can be closed and removed; Settings lists apps
An app whose page has a beforeunload handler (CoinSpectrum) could not be
closed: tabs answer the page's "stay?" request, app windows had nothing
listening, and Electron reads silence as a veto. Closing the window is now
always the user's call; a reload or navigation inside the app asks, as a
tab does.

Removing it looked dead for a related reason. The confirmation was drawn
as Theseus's sheet in the main window, where the user was not looking (or
nowhere, with the main window closed), and the removal then closed the app
window with the same call the page vetoes. The question is now asked on
the app window that asked, and removal destroys the window.

Installed apps were only reachable from the address-bar chip while on the
site. Settings gets an Apps page, at theseus://settings/apps, that lists
them with Open and Remove and follows installs, removals and open windows.
The three list calls it uses are settings-only now.
