Fix embedded Postgres initdb failure in Docker slim containers

Browse source 
The embedded-postgres library hardcodes --lc-messages=en_US.UTF-8 and
strips the parent process environment when spawning initdb/postgres.
In slim Docker images (e.g. node:20-bookworm-slim), the en_US.UTF-8
locale isn't installed, causing initdb to exit with code 1.

Two fixes applied:
1. Add --lc-messages=C to all initdbFlags arrays (overrides the
   library's hardcoded locale since our flags come after in the spread)
2. pnpm patch on embedded-postgres to preserve process.env in spawn
   calls, preventing loss of PATH, LD_LIBRARY_PATH, and other vars
