fix(Metric): canonicalize attribute order in series keys

[kitlangton]

Why

Metrics with the same id and equal attributes could create separate series when the attributes were inserted in a different order.

What changed

• Canonicalize attribute order when building registry keys, using an in-place sort over the fresh entry array.
• Cover record, wrapper, contextual, and metric/context merge order in Metric.test.ts.
• Preserve caller and public metadata order.

Verification

pnpm lint-fix
pnpm test --run packages/effect/test/Metric.test.ts packages/opentelemetry/test
pnpm --filter effect check
git diff --check

Closes #7992
Closes EFF-1221
