Add serviceclientprefs, an optional feature that stores and loads the desktop clients' saved service launch preferences, one file per login profile. - Add GET|POST /localapi/v0/prefs/service-clients to load and save the current profile's service client prefs. - Add local client GetServiceClientPrefs and SetServiceClientPref that call the new local api endpoint. - Store the prefs with the ipn/store FileStore at TailscaleVarRoot()/profile-data/<profileID>/service-client-prefs/<hex-encoded-key>, so DeleteProfile cleans them up for free. Fall back to an in-memory store when there's no var root. - Register the feature and its local api route from build tagged files so the whole thing drops out under ts_omit_serviceclientprefs. - Add the serviceclient package holding Pref and Prefs (saved client, username, database name, and last used time), so the local api client and desktop apps can import the types without the feature machinery.
