feat(orders): show where an Uber trip went, in the list

Five rows all reading "Order - Uber Trip" are indistinguishable — the list gives
you a date and an amount and nothing to tell one ride from another (user,
2026-07-27). Where the trip went is exactly what separates them, and it was
already stored on expense_metadata.route since this morning; nothing in the list
read it.

getTransactions now joins the receipt (both directions — transaction_id OR
matched_transaction_id, since a card-settled order points at the statement line
instead) and the description cell renders "Terminal 2, Melbourne Airport (MEL)
→ 19 Lady Penrhyn Dr" in the same italic sub-line notes use.

Two deliberate limits:

- **A note the user wrote always wins.** This only fills an empty sub-line; it
  never occupies the notes field, which is theirs.
- **Deliveries are excluded.** Their merchant already identifies them, so the
  restaurant's street address would be clutter on every food order. Gated on
  platform = 'uber'.

The summary keeps the first two comma-segments of each address — a truncation,
not a guess about geography. Uber puts the venue or street first, which is the
identifying part; the full stops with their times stay in the title attribute.
