Fix day pass "Pass Not Found" error by using full Stripe session IDs (#53)

The activation API was truncating payment IDs to 6 chars, but guest day
passes stored the full Stripe session ID in Airtable. This mismatch
caused lookups to fail, showing "Pass Not Found" to customers.

Also fixes member day pass: stores full session ID instead of truncated,
and corrects the checkout redirect query param from payment_id to id.
