Erik JohnstonandClaude Opus 4.8 7cc50003b1 Add a connection-checkout timeout to the native Rust Postgres pool ...

A checkout from the Rust connection pool (`ConnectionPool.connect`) previously
blocked indefinitely while waiting for a free slot or establishing a new
connection, so an unreachable or overloaded server could hang the worker
threads handling requests forever.

Bound the whole checkout with a configurable timeout: deadpool's `wait` and
`create` timeouts (enabled via its `rt_tokio_1` runtime feature, driven on our
own tokio runtime). Hitting it raises an OperationalError, which Synapse
already treats as a retryable operational error.

Configurable via the `pool_checkout_timeout` database option (milliseconds;
default 30s, `0` disables), read by the Rust engine and plumbed to both the
connection pool and the bootstrap (pool-of-one) connection.
