test(browser): seed resets on a scratch copy and publish them in one commit (#384)

Browse Source 
The concept and plain resets made hundreds of committed transactions on the
live database; on a slow CI disk they queued behind WAL checkpoint syncs and
took 30+ s. Each reset now copies the live database into a scratch database
(backup API, no syncs), runs the unchanged seeder against it through an API
proxy, and replaces the rows of the tables the seed changed in one live
transaction. A commit by another live connection meanwhile fails the reset.

tests/browser/reset_equivalence.py proves every reset kind leaves the same
rows, files and response as the old path (PM_TEST_SEED_ON_LIVE=1).
