feat(settings): optional "Calendar" launcher name (#44)

Browse Source 
Add a Settings → Appearance toggle that switches the app's launcher label
between "Calendula" and "Calendar", for users on launchers that can't rename
apps themselves.

The launcher entry moves off MainActivity onto two <activity-alias> components
(DefaultNameAlias / CalendarNameAlias); exactly one is enabled at a time via
PackageManager.setComponentEnabledSetting. MainActivity keeps every other intent
filter; the android.app.shortcuts meta-data moves onto both aliases so the
long-press shortcut still publishes. Component-enabled state is the single source
of truth — no persisted preference.

The ComponentName uses the applicationId for the package (carrying the
.debug/.releasetest suffix) and the namespace for the class, since manifest
".Alias" names resolve against the namespace; switching to Calendar enables the
target alias before disabling the other to avoid a zero-entry launcher transient.
