* [web] Fix preview next-invoice date for cadence-change upgrades
When upgrading from a monthly plan to an annual plan (or vice versa) the
user pays for a full new-cadence term today, so the next payment is one
new-term-length from now — not the current cycle's period end. Previously
we always echoed subscription.periodEnd in the preview, which surfaced
the stale current-cycle date and misled the user into thinking they'd
be charged again ~25 days later.
makeChangePreview now compares the current and next plans' annual flag:
on a cadence flip it returns now + 1 year or now + 1 month; otherwise it
keeps the existing behaviour.
Closes#33283.
