[client] Make netbird up wait for the daemon to become ready

The CLI up path only tolerated a not-yet-ready daemon via a 10s blocking
dial, so "netbird service start" immediately followed by "netbird up"
(e.g. a container entrypoint) failed with a generic "daemon not running"
error. The container entrypoint worked around this with a shell poll loop
(status --check live) before running up.

Move the readiness wait into the CLI, mirroring how the GUI already dials:

- DialClientGRPCServer now uses grpc.NewClient with a tuned reconnect
  backoff and waits for the connection to reach READY (retrying on
  TRANSIENT_FAILURE) up to a 30s deadline, instead of grpc.DialContext +
  WithBlock with a hard 10s timeout.
- up now polls Status via waitForDaemonStatus, retrying while the RPC is
  Unavailable (socket up but service not yet registered).

Add an explicit daemon-ready signal so clients can wait deterministically
instead of heuristically:

- New optional StatusResponse.daemonReady field (field 5, wire-compatible
  with older GUIs/daemons which leave it unset). Regenerated with the
  pinned protoc v33.1 toolchain so no version churn leaks into the diff.
- The server sets ready once Start succeeds and the DaemonService is
  registered (SetReady, called from the service controller).
- waitForDaemonStatus waits for daemonReady=true (or an already-Connected
  status), with a bounded grace window so older daemons that never set the
  field are not blocked.

Simplify the container entrypoint accordingly: drop the readiness poll
loop (up now waits) and the now-dead NB_ENTRYPOINT_SERVICE_TIMEOUT env,
keeping only the daemon+up process glue and SIGTERM forwarding for clean
shutdown.
