TTL >24h has a confusing interaction with auto start

As a user, if I set my template TTL to 27h and my auto-start to daily at 9am, my workspace schedule behavior looks like this:

1. Start at Mon 09:00am
2. Stop  at Tue 12:00pm
3. Start at Wed 09:00am
4. Stop  at Thu 12:00pm
etc.

I think we can all agree this is confusing.

Limit max TTL is 24h across the board
- Caveat: this restricts the power of TTL when auto-start is unset
- Variation: only restrict the TTL when auto-start is enabled
Reset countdown on each auto-start, so TTLs >24h never trigger
