Alex Garcia d69894d094 Emit db.query spans from the three write entry points
execute_write(), execute_write_script() and execute_write_many() were the
only Database methods that ran SQL without producing an OpenTelemetry
span, so any instance doing writes - which is every instance, since
Datasette builds its internal catalog through these methods at startup -
showed reads in a trace and nothing else. The same db.system,
db.namespace and db.query.text attributes the read path already sets now
appear here, with db.query.text going through sql_attribute() so
attacker-supplied SQL cannot put an unbounded string on a span.

execute_write_many() records the parameter-set count as
datasette.param_sets, not datasette.rows_returned. executemany() consumes
parameter sets and returns no rows at all, so a rows_returned name would
be describing something that does not exist - and a consumer building a
"rows written" dashboard on top of it would be charting the wrong number.

These spans only cover the event-loop side of a write. The time actually
spent waiting on the write queue and executing on the write thread is not
attributed yet; that needs context propagation across the thread
boundary and lands separately. Writes with block=False are worse still -
execute_write_fn returns before the write happens, so the span closes
early. Span links fix that later.

As with the read path, the existing `with trace(...)` wrappers stay put
and the new spans nest inside them, so ?_trace=1 keeps working
unchanged - including execute_write_many's `count`, which the old tracer
stashes through the context manager's return value.
