feat(debug): Make data reliable when debuging

[jrosendahl-opt]

Summary

When you are debuging a page the sampling and a/b infrastructure get in the way. This change makes it so when you are in debug mode you are also in the production group and there is no analytics sampling.

• Analytics sampling: shouldSample() now returns true immediately when optableDebug is set, regardless of the configured samplingRate
• AB test group: optableDebug forces the production/treatment group, same as optableControlGroup=0 — explicit optableControlGroup=1 still takes priority
• Bot detection: SkipTargetingForBots() returns false immediately when optableDebug is set, so targeting always runs even in bot-like environments (e.g. headless browsers during development)

Activated via ?optableDebug URL param or sessionStorage.setItem("optableDebug", "1") in the browser console, using the existing flags system.

Test plan

• optableDebug in sessionStorage causes shouldSample() to return true even with samplingRate: 0
• optableDebug forces production group assignment even when random bucket would land in control
• optableControlGroup=1 overrides optableDebug (explicit control override still works)
• SkipTargetingForBots() returns false when optableDebug is set
• All existing tests pass (npx jest)
