Disable top-k/top-p by default, remove derived constants from Open WebUI valves

Set top_k=0 and top_p=1.0 across config, all deployments, and Open WebUI
filter so the full vocabulary is available to entropy-driven selection by
default. Remove population_mean, population_std, and uniform_clamp_epsilon
from the Open WebUI filter valves since these are mathematical constants
derived from the byte distribution, not user-tunable parameters.
