🧰 Bug fixes 🧰

• exporter/debug: Guard from out of bounds profiles dictionary indices (#14803)

• pdata/pprofile: create a copy when the input is marked as read-only (#15080)

• pkg/otelcol: Fix missing default values in unredacted print-config command by introducing confmap.WithUnredacted MarshalOption. (#14750) Resolves an issue where the unredacted mode output omitted all default-valued options. By introducing a new MarshalOption to disable redaction directly at the confmap encoding level, the unredacted mode now preserves all component defaults natively without requiring post-processing.

• pkg/service: Headers on the internal telemetry OTLP exporter are now redacted when the configuration is marshaled (#14756)
