feat: Add Codex OAuth FAST mode toggle (#2210)

* Add Codex OAuth FAST mode toggle

* fix(codex-oauth): default FAST mode to off to avoid surprise quota burn

service_tier="priority" consumes ChatGPT subscription quota at a higher
rate. Users must now opt in explicitly rather than inherit FAST mode
silently when this feature ships.
