The read replica never received the operator's DB pool settings, so its
Prisma pool fell back to `num_physical_cpus * 2 + 1` and the configured cap
was not enforced. Both startup paths now pass the same params to the reader:
the CLI, and the componentized entrypoints that go through
`DatabaseURLSettings.apply_to_env`.
Only pool and timeout params are inherited, through a single allowlist both
paths share. Anything that decides which tables a query resolves against
stays on the writer, including entries smuggled in through
`database_extra_connection_params`, so a writer `search_path` cannot repoint
reader queries. Params the operator pinned on the replica URL still win.
