Timers module: live ProPresenter timers and LTC timecode

New propresenter-timers module: polls /v1/timers + /v1/timers/current
(shapes verified against openapi.propresenter.com), probes the
undocumented /v1/timecode/status for LTC and honestly reports
"not available on this ProPresenter" when absent. Per-tile timer/LTC
selection via a Timers ▾ header menu (never-seen timers default on),
responsive auto-sized cards with state-derived colors (the API exposes
no per-timer color), unmistakable overrun. Includes tools/pp-timers-mock.js
for developing without a real ProPresenter.
