[client] Do not run up cmd if not needed in docker (#4508)

optimizes the NetBird client startup process by avoiding unnecessary login commands when the peer is already authenticated. The changes increase the default login timeout and expand the log message patterns used to detect successful authentication.

- Increased default login timeout from 1 to 5 seconds for more reliable authentication detection
- Enhanced log pattern matching to detect both registration and ready states
- Added extended regex support for more flexible pattern matching
