The `service.allowiconchanges` config option was ignored. On the web ui the
value injected into index.html by the api was immediately overwritten by a
hardcoded `window.ALLOW_ICON_CHANGES = true` in a later inline script, so the
configured value never took effect. The desktop app never received the
injected value at all, since it serves the bundled frontend from its own local
server and only talks to the api for data.
Expose the option via the /info endpoint and read it from the config store,
which is the only channel that reaches both the web ui and the desktop app.
The brittle window injection and its hardcoded default are removed in favor of
this single source of truth.
