brave_rewards::IsDisabledByPolicy() was hardcoded to return false on
Android regardless of the managed kDisabledByPolicy pref, so every
native call site that gates on brave_rewards::IsSupported() failed to
suppress for Brave Origin subscribers (and enterprise admins setting
the BraveRewardsDisabled policy).
Symptoms fixed:
- Ads service kept initializing on Android for Origin profiles
(AdsServiceFactory::GetForProfile gates on IsSupported).
- NTP sponsored background images and sponsored rich-media takeover
rendered (downstream of the ads service via ViewCounterService).
- DAY_10 / DAY_30 / DAY_35 Rewards retention notifications fired
(RetentionNotificationPublisher gates on rewardsNativeWorker
.isSupported).
Java-side Rewards UI surfaces were already correctly gated via
BraveRewardsPolicy.isDisabledByPolicy(profile) and are unaffected.
Also decouples BraveVpnUtils.isRegionSupported() from
BraveRewardsNativeWorker.isSupported() — otherwise the guard flip would
cause VPN UI to hide for any profile where Rewards is policy-disabled
as a side effect. Added BraveVpnNativeWorker.isSupportedRegion that
does the OFAC region check directly via brave_l10n.
