📄 Description

Describe your changes

NB_LAZY_CONN_INACTIVITY_THRESHOLD was parsed with strconv.Atoi, i.e. as a bare
integer number of minutes. The documentation, however, states it takes a Go duration
(e.g. 30m, 1h). As a result any documented value such as 30m or 5m failed to
parse and silently fell back to the 15m default, so the setting appeared to have
no effect.

inactivityThresholdEnv() now parses the value with time.ParseDuration, matching
the docs. A bare integer is still accepted as a number of minutes for backwards
compatibility, and an unparseable value logs a warning and falls back to the default.

Added TestInactivityThresholdEnv covering Go-duration values (30m/1h/90s), the
bare-integer minutes fallback, and zero/negative/garbage inputs.

Checklist

Is it a bug fix
Is a typo/documentation fix
Is a feature enhancement
It is a refactor
Created tests that fail without the change (if possible)
This change does not modify the public API, gRPC protocols, functionality behavior, CLI / service flags, or introduce a new feature — backwards-compatible bug fix that aligns the env parsing with the already-documented behaviour.

Documentation

Select exactly one:

I added/updated documentation for this change
Documentation is not needed for this change (explain why)

The docs already document the Go-duration format (30m, 1h); this change makes the
code honour it, so no docs update is required.

Summary by CodeRabbit

New Features
- Inactivity thresholds now support Go duration formats such as 30m, 1h, and 45s.
- Existing numeric values remain supported and are interpreted as minutes.
- Invalid or non-positive values now generate a warning and are safely ignored.
