fix(test): stabilize crashtracker_segfault_disabled test and isolate RC requests in request-replayer

[Leiyks]

Problem

crashtracker_segfault_disabled.phpt was flaking because commit 32aaf0a7b started writing /v0.7/config remote-config poll requests into the same dump file as telemetry. This caused the test's broad matcher to find false positives and never time out as expected.

Fix

Request-replayer: /v0.7/config requests are now written to a dedicated rc_requests.json file and exposed via a new /replay-rc-requests endpoint, keeping /replay uncontaminated by RC traffic.

Test rewrite: replaced the fragile timeout-based negative assertion with a bounded 5 s poll that looks for is_crash: true in telemetry logs — the definitive indicator that a crash report was sent. Also added clearDumpedData() before the test runs to avoid stale entries, and suppressed segfault stderr output (2>/dev/null) so the --EXPECT-- check is not polluted by the shell message.
