v2.0.0 Stabilization Pass

v2.0.0 Stabilization Pass
The stabilization pass keeps existing gameplay logic while hardening failure paths.
Hardened
Store flow keeps entity tracking until validation and authoritative SQL state change succeed.
Store mutation rejects conflicting concurrent impound/seizure/transit/service/detached changes instead of overwriting them.
Impound payment/release uses an atomic transition and can refund the fine if another operation changed state first.
AutoSQL migrations cover Vehicle OS auxiliary tables and missing legacy columns/indexes.
Invalid legacy reservations without expiry are cleaned.
Persistent vehicle fallback scanning is less aggressive while state-bag updates remain immediate.
NUI POST handling rejects malformed/non-object JSON responses before downstream UI code uses them.
Validation performed
NUI JavaScript syntax validation.
Local NUI asset reference checks.
Internal network event registration/trigger cross-check.
Merge/conflict marker checks.
Resource/fxmanifest layout review.
Runtime-specific framework/MLO behaviour still requires staging-server validation.
