chore(compose,scripts): drop Typesense from local dev/test stacks

Search is Postgres FTS; the relay no longer reads TYPESENSE_URL/_API_KEY, so
the local stacks no longer provision or wait on a Typesense container:

- docker-compose.yml: removed the typesense service + typesense-data volume.
- deploy/compose/compose.yml: removed the typesense service, its volume, the
  relay's TYPESENSE_URL env, and the relay depends_on: typesense health gate;
  compose.dev.yml: removed the typesense port/CORS override.
- scripts/start-relay-for-tests.sh: stopped bringing up + health-waiting on
  the typesense container and stopped exporting TYPESENSE_* to the relay.
- scripts/{dev-setup,run-tests}.sh: removed TYPESENSE_* env export/printout.
- scripts/dev-reset.sh, e2e-*.sh, compose READMEs/run.sh: doc-string cleanup.

Verified: docker compose config renders cleanly for docker-compose.yml and for
deploy/compose (compose.yml + compose.dev.yml), zero typesense in the rendered
output; all touched shell scripts pass bash -n.
