fix(pro): guard ACTION_SET_ACCOUNT reducer against subscription loss

Periodic refreshAccount and other store writes could replace the account without subscription, causing Pro to drop after a day or two (#106).

 - The websocket `hello` snapshot must still send cached `installed_apps` and `game_status` even when no trainer snapshot is active yet; do not reintroduce a handshake path that returns early after `trainer_changed`.
 - Remote Play/Stop uses the websocket `remote_command` message. The bridge forwards it over `wand-remote-command` / `wand-remote-command-response`, and `installed-apps-sync.js` resolves Wand's trainer API + trainer service to launch a trainer for a `gameId` or end the current trainer.
 - Remote Play must construct Wand's real trainer launch request class (`69482.vO`) before calling `trainerService.launch(...)`. Passing a plain object launches the game process but breaks Wand's `getMetadata(vO)`-based trainer state, causing missing status, disappearing play/close buttons, and stuck loading behavior.
-- Pro activation is a C# asar patch (`EPatchType.ActivatePro`, independent of the remote panel / bridge). It rewrites three account-returning service methods to inject `subscription:{period:"yearly",state:"active"}` into the response before it reaches the store: `getUserAccount` and `setAccountWandBrandExperience` (Resolver-style, service field via `<service_name>` placeholder) and `setAccountLanguage` (`BuildSetAccountLanguagePatch` PatchFactory — captures the real param names + the original `post("/v3/account/language",{...})` expr and wraps `.then`). Pro is `am(account) = !!account.subscription` (flags/512 are irrelevant). `setAccountLanguage` is the one the original two patches missed, which is why Pro dropped on language change. If a future Wand build changes these method bodies, re-derive the regexes against the live `app-*.bundle.js` (do NOT trust `.source/new` — it is a different version).
