* sfu: add opt-in verbatim abs-capture-time forwarding
Downtrack ACT forwarding gates on an RTCP sender report and
unconditionally rewrites the capture timestamp into SFU clock domain,
which suits cross-stream A/V sync but breaks consumers that need the
original publisher capture time (e.g. end-to-end latency measurement).
Add ForwardAbsCaptureTimeVerbatim (RTC config: forward_abs_capture_time_verbatim),
off by default, which skips both the gate and the rewrite.
* fix: use DisableSenderReportPassThrough setting to also gate abs-capture-time forwarding
