fix(journal): widen events window to match prep's framing

The right rail's loadEvents was using "now → now + 14 days", which
filtered out events earlier today that had already passed. The prep
uses "today 00:00 → today 23:59" so it includes those events and
explicitly notes they're "in the past". The two surfaces talked
about different sets of events.

Widen the right rail to "today 00:00 → today + 14 days 23:59" so
events from earlier today still surface and group under "Today". The
prep and the right rail now reference the same set within today.
Events further out (next 14 days) keep working as before.
