test(otel): complete renamed-attribute coverage for DB semantics (collection.name, server.port)

Add the two remaining renamed-attribute tests so the DB suite covers the full set of
Datadog->OTel renames per the spec:
  db.sql.table -> db.collection.name
  out.port     -> server.port (validated as int when present)

The suite now has 7 rename tests (db.system.name, db.namespace, db.operation.name,
db.query.text, db.collection.name, server.address, server.port). Only rename tests are
included because the scenario is gated missing_feature everywhere (no tracer implements DB
OTel yet) — unchanged/shared attributes like span.kind and error.type would xpass, so they
belong in the OTLP-typed variant / when-active coverage instead.

ruff + Manifest.validate() + meta-tests green; 7 tests collect under OTEL_SEMANTICS_DB.
