Erik JohnstonandClaude Opus 5.5 419c47e91d Add a write transaction helper for the native pool ...

`run_write_interaction` is the Rust `runInteraction` for writes: a
`REPEATABLE READ` transaction, committed at the end, and run again from the
start on a serialization failure, a deadlock, a cancelled statement or a
lost connection, up to five attempts as in Python. Constraint violations come
back as their own error, so an expected conflict can be told apart.

Once a statement fails, Postgres has aborted the transaction, and a COMMIT
would roll back without an error. So if the closure catches a statement
error and returns success, the commit is refused with an error.

`WriteTxn::insert_many` and `upsert_many` write a batch in one statement
whatever its size, passing each column as an array to `UNNEST`.
`execute_batch` pipelines a per-row statement for the inserts that need a
sub-select per row.

The tests run against a real server when `SYNAPSE_TEST_POSTGRES_DSN` is set.
