docs(trip): confirm LA Airbnb extra night, Sep 26-30

Host accepted the alteration on Sep 15 (reservation HMNBY9NYRN): 4 nights
Sep 26-30 instead of 3 nights Sep 27-30, total EUR 1,077.00 (+EUR 311.31,
paid in full). This resolves the "additional night TBC" note on Sep 26.
Cancellation is now partial-refund until Sep 19 4:00 PM PDT.

Sep 27 no longer involves a check-in, so the luggage-storage caveat and
the 4:00 PM check-in constraint on the Pantages option are gone.

Ledger: LA row US$860.00 -> US$1,209.63 (same FX rate as the original
row); settlement recomputed.
