fix: honor relative reset toggle and local tz in tray/pop-out cards

[nov30th]

Summary

• fix: render Claude reset time in local timezone, honor relative-reset toggle #37 fixed reset-time formatting in Settings → Providers, but the tray icon popup and pop-out window render through MenuCard, which still displayed snap.resetDescription verbatim (backend pre-formats Claude's DateTime<Utc> as UTC wall time) and ignored the Display → "Relative Reset Time" toggle.
• Thread resetTimeRelative through TrayPanel and PopOutPanel into MenuCard, and route both metric resets and cost.resetsAt through the existing useFormattedResetTime hook so the same local-tz / countdown logic applies in every surface.

Test plan

• Toggle Display → "Relative Reset Time" off; tray popup shows reset time in local timezone (verified with Claude account on a UTC+8 machine).
• Toggle on; tray popup shows live "Resets in Xh Ym" countdown.
• Pop-out window mirrors the tray behavior.
• Cost section's "Resets" line reformats correctly.
• tsc --noEmit and tauri build pass.

Thanks for the PR, this was the missing follow-through from #37 for the tray popup and pop-out surfaces. I added one small guard before merging so fallback reset text from providers that use it for non-time details stays unlabelled, then validated locally with frontend build/tests and a Tauri debug build. Merged into main.
