Provide component‑level bottleneck diagnostics and root‑cause metrics for CDC pipelines

Customers cannot reliably identify the exact part of the pipeline that is limiting performance. Current snapshot views only surface a generic “target database” or “Target Engine” bottleneck, and the “SOURCE communication wait” metric shows that the source was delayed by the target without revealing why. This results in lengthy manual debugging, missed latency SLAs, and unnecessary support tickets.
Requested enhancement:
1. Add a Bottleneck‑Drill‑Down panel that ranks contributors (source read, network transport, Target Engine, target DB) with quantitative percentages.
2. When the Target Engine is flagged, surface detailed sub‑metrics (CPU, I/O, queue depth, index‑maintenance, Fast‑Apply queue) to explain the root cause.
3. Extend the “SOURCE communication wait” metric to include the specific target‑side delay reason.
4. Expose these diagnostics via the Management Console and an API so downstream monitoring tools can consume them.
