Simplificar a "FAB abre modal nativo" y añadir hora fin sesión

El usuario prefiere ver la página de Uso nativa de Claude en vez de un
overlay propio. Eso permite borrar mucho código:
- Fuera openOverlayPanel, closeOverlayPanel, setOverlaySpinner,
  renderOverlayWithCache, showOverlayError.
- Fuera refreshInBackground, tryOpenViaPushState/Hash/Click,
  closeUsageModal, waitForDialogWithData — ya no auto-abrimos en
  background.
- Fuera formatAge y CACHE_TTL_MS y OVERLAY_ID y refreshPromise.
- Fuera __claudeUsageTracker (era andamio de debug).
- Fuera bloque de CSS del overlay (~120 líneas).

Nuevo onFabClick: 3 intentos en cascada para abrir el modal nativo de
Claude (hash → pushState+popstate → click en "Uso"). Si los 3 fallan,
warn en consola y queda el manual.

Y siguiendo lo que pediste, en el resumen del tracker (el que se
inyecta dentro del modal) ahora aparece un bloque azul "⏱ Sesión
termina a las HH:MM (en Xh Ym)" justo debajo del bloque verde del
reinicio semanal.
