feat: add tollgate_core component + market config wiring

- Add tollgate_core ESP-IDF component (skeleton: cashu, dns, firewall, session)
- Add tollgate_platform.c with SPIFFS config backend
- Wire market_enabled, market_scan_interval_s, client_auto_switch in config.c
- Add lwip_tollgate_hooks.h (updated from feature branch)
- Add E2E fix plan, tollgate_core design doc, WPA autodetect plan
- Add integration test network helpers
- Add CONSOLIDATION.md plan

Reverts the broken merge (be4788b) that gutted config.c/tollgate_main.c/tollgate_api.c
and replaces it with a clean addition on top of intact master.
