Fix quota reset countdown after Wake and Refresh

[squarepots]

What changed

Quota reset countdowns synchronize their clock before painting when a refreshed reset timestamp arrives. Cards keep their DOM identity and keyboard focus, and continue updating once per minute.

Why

Wake and Refresh could otherwise show a newly started five-hour window as 5h 1m by combining the new reset timestamp with a clock sampled up to a minute earlier. The same mismatch could leave an elapsed reset displaying a future countdown.

Validation

• Reproduced both update paths and the elapsed-reset bug in regression tests before applying the fix.
• 157 frontend tests passed with pnpm test --exclude '.claude/**'.
• TypeScript and the production frontend build passed with pnpm build.
• Version synchronization and git diff --check passed.
• Strict Mode coverage checks timer cleanup and preserved DOM/focus; formatter coverage keeps real durations above five hours visible.

Remaining

The unfiltered local source-proof command scans unrelated nested worktrees and fails there; remote CI runs from a clean checkout. Real-account release acceptance has not been performed. No provider protocol, credentials, account state, or version changes are included.
