feat(export-ui): mount the export button on the eight remaining list pages

customers, contracts, invoices, payments, train schedules, and locomotives /
trains / wagons via the fleet page's config.

FilterBar pages pass controls.params into the children slot. The four pages
still on ad-hoc filtering pass their own hand-built filter object instead,
which is why ExportButton takes plain params rather than a UseFilters — it
would otherwise have been blocked behind migrating those pages. FleetResource
serves seven slugs from config, so it gets an optional exportKey there and
renders nothing for the four slugs with no dataset yet.

Auditing each page's real filter keys against the dataset declarations turned
up three gaps where an on-screen filter would have silently not applied to the
export: invoices sends a singular "status" (the dataset only had the
multiselect "statuses"), contracts sends paymentCurrency, serviceTypeId and
route origin/destination, and train schedules sends freightType. Added all of
them — contract routes filter through EXISTS on contract_routes since they are
one-to-many, and train-schedule freightType through EXISTS on the bookings
aboard, matching the list service.

Verified in the browser: the button renders on each page, and the invoices
dialog follows that page's own filter object — selecting Paid moves the count
from 126 to 100, which matches the database. Filter pass-through checked
against the database for invoices, payments, wagons, contracts and train
schedules.
