fix(context): forward all BucketingAttributes to ExperienceManager

Context.runExperience and Context.runExperiences rebuilt a fresh
attributes object with only four hardcoded keys (visitorProperties,
locationProperties, updateVisitorProperties, environment) before
forwarding to ExperienceManager.selectVariation/selectVariations.

This silently dropped every other BucketingAttributes field —
enableTracking, forceVariationId, ignoreLocationProperties,
typeCasting, experienceKeys — so callers opting out of tracking,
forcing a variation, or ignoring location targeting were silently
ignored. DataManager._getBucketingByField destructures these by name
with enableTracking defaulting to `true`, which is how the opt-out
was being lost.

Switch to spread-then-override so all caller-supplied attributes pass
through while still applying the two transforms Context must do:
merging visitorProperties via getVisitorProperties() and defaulting
environment to the Context's own environment.

Add tests covering forwarding of enableTracking, forceVariationId,
ignoreLocationProperties, and updateVisitorProperties through both
runExperience and runExperiences.
