feat(pi): move rarely used provider settings into a collapsed advanced section

Request headers, omp model discovery and compat options now sit in a
collapsed "Advanced Options" section below the model list, matching the
Claude Code and Codex forms. It stays collapsed even when a preset fills
compat values.

The compat and discovery hints are rewritten in plain language, and the
discovery types get readable labels instead of raw omp identifiers. The
discovery select ignores an empty value, which Radix can report when it
mounts inside a form.
