Summary

Enhances the Keep Awake (idleInhibit) utility card to adaptively format and display the active inhibition duration across minutes, hours, days, and weeks, replacing the static time-of-day clock timestamp.

Design & Architecture

Following maintainer review:
• Retains the transient RuntimeState architecture (inhibitIdle and inhibitingIdleSince), ensuring the idle inhibitor remains session-scoped by design.
• Preserves upstream module naming and IPC APIs (idleInhibitor target, isEnabled, enable, disable, toggle).
• Retains the active duration indicator bound to RuntimeState.inhibitingIdleSince.

Duration Formatting

Implemented formatActiveDuration(activeSince: real) in modules/utilities/cards/IdleInhibit.qml:
• < 1 hour: Active for %n minute(s) (e.g. Active for 35 minutes)
• < 1 day: Active for %n hour(s) (e.g. Active for 5 hours)
• Multiple days: Active for %n day(s), %n hour(s) (e.g. Active for 3 days, 4 hours)
• Weeks: Active for %n week(s), %n day(s) (e.g. Active for 2 weeks, 3 days)
• Safely handles missing/invalid (<= 0) timestamps (Active) and future timestamps (Active for 0 minutes).
• Respects pluralization and translation conventions (Tr.tr, Tr.trN, and Tr.trCtx).
• Bound component compliance with pragma ComponentBehavior: Bound.

Verification

• Build: Built cleanly with cmake --build build (Ninja).
• C++ Formatting: clang-format --dry-run --Werror passed on all C++ files.
• QML Formatting: qmlformat matched with 0 diff.
• Conventions Lint: python3 scripts/qml-lint-conventions.py checked 282 files with 0 violations.
• Translations Lint: python3 scripts/trs-check.py checked 436 files with 0 issues.
• Live Quickshell / Wayland Session: Tested under active Hyprland session verifying formatting across all duration scales, invalid/future timestamps, and transient toggle behavior.
