fix(dashboard): parse Codex reset_at as epoch ms or seconds

Codex returns weekly window reset_at in milliseconds in some cases,
which was being multiplied by 1000 and producing nonsensical reset
countdowns and pace calculations. Route through _parseResetTimestamp
so both formats work, and add a regression test.

Also tightens comments in useMobileKeyboard / ChatView around why
visualViewport scroll events skip offsetTop updates.
