Uphold doesn't always get the "Disconnected" UI/Disconnected (Verified) state correctly

[LaurenWags]

Description

When you naturally disconnect from Uphold you should see the "Disconnected" UI (different from explicit disconnect). However, depending on whether you access rewards panel or brave://rewards page first is determining whether you get the proper UI/state.

Does not reproduce with Gemini in 1.29.x.

Does not reproduce with 1.27.x or 1.28.x with Uphold.

Steps to Reproduce

1. Clean profile, non-Japan region, staging environment.
2. Enable Rewards
3. Link a KYC'd Uphold wallet
4. Confirm wallet is linked (balance shows in browser, etc)
5. Navigate to Uphold site (make sure brave://rewards page is closed if open in any tabs)
6. Revoke Brave-Browser access to simulate natural disconnect
7. Open panel
   --> No "Disconnected" UI, see "Verify wallet" instead
   --> Open brave://rewards page, no "Disconnected" UI, see "Verify wallet" instead
   --> Open brave://rewards-internals, see Wallet status as Not connected

If at step 7 you open brave://rewards page instead of the panel, you correctly get "Disconnected" UI on rewards page, panel, and internals page (wallet status is "Disconnected (Verified)").
