Why

#67 lets someone add accounts by hand, but a phrase restored from another Quantus wallet already has the accounts it has: the mobile wallet numbers them and its import runs a BIP-44 gap-limit scan over both schemes to find the ones that exist on chain. Restore here opens account 1 only, so a person who kept their funds on account 2 or 3 sees an empty wallet and has to guess how many times to press "Add account".

Scope

After a restore, and from a "Find accounts" button on any open wallet that carries a phrase, scan account numbers under both schemes on the selected chain: derive the addresses, ask the chain which of them exist (System::Account present), and keep scanning while any number in the last batch existed, stopping after a gap of consecutive empty numbers (the mobile wallet uses 20).
Every number found is opened in the session and remembered in settings, exactly as "Add account" does, so it comes back on the next unlock.
The scan reads existence for a batch of addresses in one request, and says what it found ("2 more accounts" / "nothing beyond account 1").
A chain that is not connected, or a wallet with no phrase, offers no scan.

Not in scope

Scanning for wormhole deposits: those are found by the leaf scan already, and a wormhole address is derived per wallet, not per account number.

Acceptance

On the dev node: fund account 3 of a phrase from another wallet, restore that phrase here, and the accounts page shows accounts 1 to 3 with account 3's balance, without pressing anything. On a phrase with nothing beyond account 1, the scan adds nothing and says so.
