SimpleFin Sync v1.3.1

Fixes a flaw in v1.3.0's Fix baseline, found live the day it shipped.

A bank balance that already includes a posted transaction SimpleFin's transaction list has not reported yet produces the exact signature v1.3.0 read as a wrong baseline: a gap no stored transaction explains, constant across the whole window. The offer was taken, the feed caught up hours later, and the account double-counted $1,300.

What tells the two apart is time — a wrong baseline has been wrong since the day it was written and never resolves itself, while feed lag clears in days. The offer now also requires the account's drift to have been standing for at least 10 days. A genuine baseline error still gets its offer; it just arrives once feed lag has been ruled out by waiting longer than lag can plausibly last.

If you accepted a Fix baseline offer on v1.3.0 and the drift later reappeared reversed, the feed caught up behind it: revert the starting-balance row to its previous amount and keep the newly imported transaction.

Requires Wealthfolio 3.6.2 or later.
