There is one PocketBase instance and it is hosted. Removes the `npm run pb`
script, which started a local server nothing used.
The schema had two apparent sources of truth. scripts/setup-remote.ts is the
one that actually runs; pb_migrations/ only executes on PocketBase server
start, which never happens here. Both now say so, so nobody edits a migration
and believes the schema changed.
