[client] Drop the initial GetNetworkMap fetch on Android startup

Android startup opened a throwaway Sync stream to management before
creating the TUN device, only to learn the initial routes, DNS config
and the DNS feature flag. Server side this computed a full network map
and broadcast a false connect/disconnect pair to every peer in the
account on every Android start; client side it put a blocking network
round trip on the critical startup path and failed the whole engine
start when management was unreachable.

None of its outputs are needed upfront anymore: the TUN is created
empty and the first sync triggers a rebuild that pulls the fresh route
and search domain state, the permanent DNS server starts with an empty
config that the first sync populates, and the fake IP manager is
created lazily when the DNS feature flag turns on.

Remove readInitialSettings and its plumbing: the InitialRoutes and
DNSFeatureFlag manager config fields, the android construction-time
route setup, the initial-route bookkeeping in the notifiers and the
now-unused GetNetworkMap client method.
