Import the longest bank-permitted history and surface real provider errors

Browse Source 
Manual history imports failed opaquely once a bank capped lookback on an
established consent (N26 rejects date_from beyond ~90 days with
WRONG_TRANSACTIONS_PERIOD). Backfill now requests the documented longest
fetching strategy, reports the coverage the bank actually provided, and
non-2xx responses surface allowlisted documented error codes instead of a
generic fallback. Dead-session codes map to reconnection. Failed syncs
retry hourly so a stale sync banner no longer persists for a day.
