The ticket-vouchers lookup previously returned the tier entitlement
every time, so a donor could keep claiming free tickets by re-
submitting the form. It now subtracts vouchers already consumed:
remaining = entitled - used
where `used` is the sum of the Vouchers column across that donor's
prior ticket orders (each checkout stores what it applied). Response
gains entitled/used/remaining; `vouchers` is now the remaining count
the form should grant. Consumption is implicit — no counter to keep in
sync — and resets by zeroing/deleting the Vouchers value on the order
row in NocoDB.
- nocodb: findByEmail + vouchersUsedByEmail (case-insensitive).
- 8 new tests (36 total). Doc updated with the new response + reset.

Move the ticket-voucher API into its own standalone doc
(docs/fluentforms-ticket-vouchers.md) — endpoint, 0/1/2 rules, config, form
snippet, and curl test — so it's easy to find and hand off for the lookup. The
donor-discount doc now links to it instead of duplicating the section.
