[BUG] Memoty leak: entities not cleaned if you generate map with WorldBorder plugin without players

[gravit0]

Describe the bug
Map generation with WorldBorder causes memory leaks due to large number of entities and tile entities that are never cleared because the server does not tick when there are no players.

To Reproduce

1. Install WorldBorder plugin
2. Start map generation without players
3. Generation stopped because memory is low

Expected behavior
It might be worth clearing entities in the absence of players elsewhere

Screenshots

Additional context

Environment (please complete the following information):

• Crucible Version: Last staging and rfb-support branch
• Plugins: WorldBorder
• Mods: None
• Java Version: 21
• OS: Linux

Well, now that you mention that, this is really a bug that i have faced like forever on Thermos/Crucible.

My main problem with this bug is related with items.
Sometimes like thousands of items are spawned on specific chunks and the amount just increase until a players come closer to the the chunk and them all of the items are removed at once.

I think this is indeed a serious problem, not only for when generating chunks, but for chunkloaders as well.
