[Bug]: Pubky profile falls back to "Your Name" after Shop Paykit setup #1344

What happened?

On a fresh mainnet wallet, a Pubky identity named pav C tester (pubkyadjn…jdcy) was created in Bitkit and used to approve Shop / Paykit. About an hour later the home header shows the Your Name placeholder and no profile. The same pubky still signs Shop authorization requests (ADJN…JDCY).

After the next process start, Paykit grant-session restore failed, re-sign-in recovery failed, and the Pubky auth handler flipped to the no-identity state (signup enabled, auth disabled). The secret key was not wiped in that window.

The home sync spinner also keeps spinning. App Status at the same time: Internet connected, Bitcoin node Could not connect to Electrum, Lightning Stopping. That part looks like #1252 / a transient network drop; the profile-name loss is the bug here.

Expected behavior

After Shop Paykit setup, the Bitkit-created profile stays loaded across restarts. A failed Paykit session restore should not make the header look like there is no identity while the key can still authorize.

Steps to Reproduce

1. Install current-master mainnet debug (2.4.1 (188), to.bitkit). Enable Paykit UI.
2. Fresh wallet. Create a Pubky profile in Bitkit (Homegate). Confirm the header shows the name.
3. On shop.pubky.app, use that identity for seller Bitcoin / Paykit setup and approve the grant in Bitkit.
4. Leave the app / restart later (here: ~1 hour, then a process start at 12:07).
5. Open home. Header is Your Name. Authorize a Shop request: same pubky and name still appear on the auth sheet.
