Coordinator is not calulating compaction taskSlots correctly

Druid is on 25.0.0 running on kubernetes.

I see one issue in auto-compaction for coordinator
when it calculates the totalSlots - It doesn't take into account the middle-manager-tiers.
We have 2 tiers.

for example:
1. compact_tier(10 MMs with 4 slots each)
2. default_tier(50 MMs with 10 slots each)
So It ignores tiers and shows maxCompactionslots to 54 which is [0.1*(40+500)]

In this log it shows wrong
`"Found [32] available task slots for compaction out of [54] max compaction task capacity"`

Start at the Coordinator's auto-compaction task-slot calculation and inspect how maximum compaction capacity is derived from middle-manager tiers. Reproduce the two-tier setup described—10 workers with 4 slots and 50 workers with 10 slots—and verify that the logged available and maximum values account for both tiers.
