Cap the liquid-test polling interval at 5 seconds

[Benjvandam]

Why

fetchResult grows the poll delay 5% per poll with no cap. For long test runs that means:

elapsed	poll interval
60s	~4s
5 min	~15s
10 min	~30s
20 min	~60s
~33 min (waitingLimit)	~100s

A liquid test that takes ~10 minutes server-side (observed in be_market CI, e.g. run 28656835005: a single test, 9m51s) is only checked every ~30s by then, so a finished run sits unnoticed for up to a minute. In CI batches that detection lag multiplies.

What

Cap the delay at 5 seconds (reached after ~70s of polling). Detection lag is now bounded at 5s; short runs poll exactly as before, and the steady-state request rate is at most one readTestRun per 5s per run.

Validation

• New unit test drives a 60-poll run through fake timers and asserts the maximum setTimeout delay is exactly 5000ms (cap reached, never exceeded).
• Full suite: 566/566 pass.

Context: follow-up from silverfin/bso_github_actions#28 (CI-side retries + parallel firms) — this is the CLI-side piece of the latency work.

state that the 5-second maximum interval applies only after the delay reaches
its cap; acknowledge that the initial 1000ms delay allows multiple polls within
five seconds.
