chore: Update non-major dependencies

[renovate]

Summary

• Bump non-major OpenTelemetry dependencies: go.opentelemetry.io/otel v1.44.0 → v1.45.0, otelgrpc/otelhttp v0.69.0 → v0.70.0, and the b3 propagator v1.44.0 → v1.45.0.
• Migrate the telemetry log instrumentation off the removed otel/log value API (log.Value, log.KeyValue, log.StringValue, …) onto go.opentelemetry.io/otel/attribute types, which log.Record now uses directly in otel/log v0.21.0.
• Restore compilation of the telemetry log channel so the module builds and all telemetry tests pass against the updated dependencies.

Why

Renovate bumped go.opentelemetry.io/otel to v1.45.0, which pulls in go.opentelemetry.io/otel/log v0.21.0. That release removed the log package's value API — Value, KeyValue, StringValue, MapValue, SliceValue, BytesValue, and the String/Int64/Float64/Map/Slice constructors are gone, and Record.SetBody/AddAttributes plus logtest.Record now use attribute.Value/attribute.KeyValue from go.opentelemetry.io/otel/attribute. The telemetry log instrumentation (telemetry/instrumentation/log) referenced the removed types, so the repository no longer compiled.

The handler and its value mapper now build attribute.Value/attribute.KeyValue directly (BytesValue became ByteSliceValue, dynamic keys are wrapped in attribute.Key, and the now-redundant ValueFromAttribute branch was dropped), keeping the exported OTel log records identical. Applications that route logs through an "otel" channel keep working unchanged after the upgrade.

// Before: the application no longer compiles after the OTel upgrade — the telemetry
// log channel cannot be built because otel/log v0.21.0 removed its value types.
facades.Log().Channel("telemetry").WithContext(ctx).
	Code("ERR_500").
	In("payment").
	Tags("api", "v1").
	With(map[string]any{"user_id": 42}).
	Info("payment processed")

// After: the same code compiles and the entry is exported to OTel as a log record
// with the same attributes (code=ERR_500, domain=payment, tags=[api v1], user_id=42).
facades.Log().Channel("telemetry").WithContext(ctx).
	Code("ERR_500").
	In("payment").
	Tags("api", "v1").
	With(map[string]any{"user_id": 42}).
	Info("payment processed")
