Implement Set Name feature (0x6d01)

- Add MemoSetName service with 77-byte UTF-8 validation and broadcast.
- Add SetNamePage controller with byte counter and navigation to /account.
- Add AccountPage controller showing stored name and Set Name button.
- Add Profiles session store to share the new name across pages.
- Add React views /memo/set-name and /account, plus nav link.
- Update acceptance handlers for set-name scenarios and fix fake wallet
  sendOpReturn signature to match public minimal-slp-wallet API.
- Update existing post memo tests to match the corrected wallet API.
