…#62870) ### What problem does this PR solve? Introduce two configurable timeouts (mirroring the BE `brpc_light/heavy_work_pool` naming) and apply them to all 8 cdc_client RPC call sites: - `streaming_cdc_light_rpc_timeout_sec = 90` for `/api/close`, `/api/compareOffset`, `/api/fetchEndOffset`, `/api/getTaskOffset`, `/api/getFailReason` (server-side single-statement queries / cache lookups, expected sub-second). Default is 90s rather than 30s to absorb cdc_client cold-start: when the BE-spawned cdc_client process is not yet running, `start_cdc_client` performs a health-check loop (worst case ~45s) before serving the request — 90s gives enough headroom to avoid spurious timeouts during this window while still bounding `JobManager.writeLock` hold time. - `streaming_cdc_heavy_rpc_timeout_sec = 600` for `/api/initReader`, `/api/fetchSplits`, `/api/writeRecords` (may legitimately take minutes for replication slot creation, large snapshot split computation, or batch writes).
