Erik JohnstonandClaude Opus 4.8 98a7e37c59 Apply per-connection session setup in the Rust connection pool ...

Move the equivalent of the engine's `on_new_connection` into the pool's
`ConnectionManager::create`, so every pooled connection is configured once when
it is opened rather than on each checkout. A new `SessionConfig` (carried by the
manager) drives it:

  - the default isolation level is set to REPEATABLE READ, matching the engine's
    `default_isolation_level`, so a plain BEGIN behaves as it did under psycopg2;
  - `synchronous_commit` is turned off when configured;
  - `statement_timeout` is set when configured.

`bytea_output` is deliberately not set: tokio-postgres uses the binary protocol
for prepared statements, so that text-format GUC is irrelevant to how we decode
bytea.

`create_pool` keeps its signature (default session); a new
`create_pool_with_session` and two new keyword-only `ConnectionPool(...)`
arguments (`synchronous_commit`, `statement_timeout_ms`) expose the settings.
