Fix spinner ticks not playing samples correctly sometimes

Noticed this during work on https://github.com/ppy/osu/pull/25185.

In some circumstances, it seemed that spinner bonus ticks (and mostly
them specifically) would not always play with the correct volume.
Hours of debugging later pointed at a trace at
`DrawableAudioWrapper.refreshLayoutFromParent()` not firing sometimes.

Initially I thought it to be some sort of framework bug, but after
preparing a diff and running final checks, I noticed that sometimes
the sample was being played *by a `PoolableSkinnableSample` that wasn't
loaded*. And determining why *that* is the case turned out with this
diff.

As it happens, spinner ticks get assigned a start time proportionally,
i.e. the 1st of 10 ticks is placed at 10% of the duration, the 2nd
at 20%, and so on. The start time generally shouldn't matter,
because the spinner is manually judging the ticks. *However*, the ticks
*still* receive a lifetime start / end in the same way normal objects
do, which means that in some cases they can *not be alive* when they're
hit, which means that the `DrawableAudioWrapper` flow *hasn't had
a chance to run*, and rightly so.

To fix, ensure that all spinner ticks are alive throughout the entirety
of the spinner's duration.
