Gave Pump Scheduling problems more accuracy at the cost of more computation time

[Trosper3]

Before:

const int Buckets = 1000 — always 1000 buckets regardless of tank size
bucketSize = cap / 1000 — each bucket represented a fraction of capacity

After:

buckets = (int)Math.Ceiling(cap) — number of buckets equals the tank capacity (in gallons)
bucketSize = 1.0 — each bucket represents exactly 1 gallon

The effect is that tank levels are now tracked at 1-gallon precision instead of cap/1000 precision. For the default 10,000-gallon tank this makes buckets 10× finer (10,000 vs 1,000), but the real benefit is correctness — the bucket count now scales with the actual tank size rather than being an arbitrary constant. The change appears in both the CM and EM solvers, and in two separate DP methods within the EM solver.
