wallet: the deterministic parse must beat the model's location

Found by reading the backfilled rows rather than by a test. The precedence
was subtitle -> MODEL -> descriptor, so the model's answer won wherever it
had one, which is always. That defeats the entire point of parsing the
descriptor positionally: the ledger got "SAN FRANCISOUS" for the only
foreign merchant in the capture window, plus the padded "MELBOURNE   AU",
and the bare "Sydney"/"Perth" with their country codes dropped.

Correct order is subtitle -> deterministic descriptor -> model. After the
fix those rows read SAN FRANCISO US, MELBOURNE AU, Sydney AU, Perth AU,
and a subtitle-derived place still wins where one exists.

The test that should have caught this passed because its fixture omitted
`location`, so the fallback chain was never exercised — every real
interpretation carries one. Fixture now includes the model's actual
mangled answer for that row, so the test fails if the order regresses.

Re-ran the backfill on the corrected code: 21 transactions, $6,284.37
unchanged, 13 with a location. The 21 previously-written rows were deleted
first rather than superseded, which is normally forbidden on transactions
— checked before doing it that they carried zero splits, tags and
overrides, being machine-written minutes earlier by this same lane with
nothing yet attached.
