Feature: Interactive Web Dashboard, OCPP 2.1 V2G/ISO 15118, Advanced EV Simulation, and mTLS Security

[Bravos-hub]

This pull request brings an extensive suite of enhancements to the OCPP Virtual Charge Point, transforming it into a fully-featured, interactive, and advanced testing simulator for modern EV Charging scenarios.

Major Features Included:

1. Interactive Web Dashboard 🌐
   Added a responsive, modern React-based Admin UI running alongside the VCP (accessible via browser).
   Features a Trace Viewer to monitor incoming/outgoing OCPP messages and payloads in real-time.
   Allows sending Admin commands (Auth, Start, Stop) directly from the interface instead of via terminal scripts.
2. Advanced EV Simulation Modes 🔋
   Dynamic Battery Curve:
   MeterValues
   generation now incorporates a simulated Electric Vehicle Battery (Battery Capacity, Target SoC%). Uncapped charging curves are applied automatically to mimic real-world energy draws.
   Smart Charging Compatibility: Handles incoming
   SetChargingProfile
   requests to dynamically throttle the simulator's charging consumption based on CSMS-defined limits.
   Chaos Mode: Added a toggle to simulate deterministic physical hardware faults and randomized WebSocket connection drops to test CSMS resilience and offline persistence behavior.
3. Enhanced Security (OCPP Security Profile 3) 🔒
   Mutual TLS (mTLS): Implemented full client-side certificate support to establish secure TLS connections to the CSMS.
   Certificate Lifecycle Management: Added native workflows to automatically generate Certificate Signing Requests (CSR) via the
   SignCertificate
   and
   CertificateSigned
   events.
   Security Events: Introduced persistent storage and transmission of anomalous network events via
   SecurityEventNotification
   .
4. Full OCPP 2.1 Support (V2G & ISO 15118) ⚡
   Plug & Charge (ISO 15118): Deeply integrated support for simulating eMAID identity tokens and ISO15118CertificateHashData during the .Authorize and
   Get15118EVCertificate
   exchanges.
   Vehicle-to-Grid (V2G/V2H): The EV Battery simulator now safely handles bidirectional power flows (i.e. negative charging limits) to discharge into the grid. Mapped native UI controls to negotiate complex V2G requirements via
   NotifyEVChargingNeeds
   .
   Extended Device Model: Fully wired the
   GetVariables
   ,
   SetVariables
   , and
   GetBaseReport
   handlers to map strictly to persistent SQLite storage representing physical controllers (e.g. AuthCtrlr, OCPPCommCtrlr).
   Technical Changes
   Initialized an integrated Vite/React ui/ layer built to serve statically from the main backend.
   Migrated core temporary states to a local persistent better-sqlite3 data layer (
   vcp.db
   ) to withstand hard reboots without losing transaction context, configurations, or certificates.
   Extensively reworked the
   TransactionManager
   logic loop to be more robust.
