ci: install pgtap extension and run full flows-db seed

pgtap was missing from the DB so test is() functions failed. Add it to
ci-bootstrap.sql. Switch flows migrations to env=local so
generate_register_intervals is created, allowing the full flows seed to run
(needed by tests that check specific row counts).
