UI: a role denied one non-essential bootstrap API (e.g. listLdapConfigurations) fails to load the entire console

### problem

The web console fails to load entirely for any role denied one non-essential bootstrap read. [`GetInfo`](https://github.com/apache/cloudstack/blob/main/ui/src/store/modules/user.js#L326) runs several independent calls under a single shared `Promise` and wires several to the same `reject`, including [`listLdapConfigurations`](https://github.com/apache/cloudstack/blob/main/ui/src/store/modules/user.js#L493-L497), which only sets a flag. When a role denies it the 432 rejects the shared promise before [`listApis`](https://github.com/apache/cloudstack/blob/main/ui/src/store/modules/user.js#L415) can resolve it (a race the small query usually wins), so `GetInfo` rejects and the [router guard](https://github.com/apache/cloudstack/blob/main/ui/src/permission.js#L150-L167) logs the user out instead of building routes. The tolerant pattern sits right beside it: [`listNetworkServiceProviders`](https://github.com/apache/cloudstack/blob/main/ui/src/store/modules/user.js#L485) swallows its own error and the console still loads (`listGuiThemes` likewise).

**Expected:** a denied non-essential read degrades like `listNetworkServiceProviders`/`listGuiThemes`. **Actual:** blank console, redirect to `/user/login`.

### versions

4.22 and current `main`. Client-side UI only; hypervisor/storage/network irrelevant.

### The steps to reproduce the bug

1. Create a custom role (e.g. from the DomainAdmin base type) that denies `listLdapConfigurations`.
2. Assign an account to it.
3. Log in to the web UI — the console never renders and you are redirected to login.

### What to do about it?

Give `listLdapConfigurations` (and any non-essential bootstrap read) its own `.catch` that defaults the flag, as [`listNetworkServiceProviders`](https://github.com/apache/cloudstack/blob/main/ui/src/store/modules/user.js#L485) already does. The underlying hazard is the shared `resolve`/`reject` across independent calls in `GetInfo`; reserve `reject` for genuinely essential calls such as `listApis`.

Inizia da ui/src/store/modules/user.js, in GetInfo, soprattutto da listLdapConfigurations e dagli handler tolleranti listNetworkServiceProviders/listGuiThemes. Controlla ui/src/permission.js per capire il percorso di errore del route guard. Il lavoro è completato quando una lettura di bootstrap non essenziale negata imposta il relativo flag al valore predefinito senza rifiutare GetInfo, così la console viene caricata invece di eseguire il redirect a /user/login.
