Switch from ESP-IDF Log V1 to V2, which centralizes log formatting inside esp_log() instead of expanding esp_log_timestamp(), color codes, and LOG_FORMAT() at every ESP_LOGx macro call site. This saves ~9KB of flash by eliminating ~500 per-site macro expansions in ESP-IDF library code (gpio, ethernet, mdns, uart, wifi, etc.). Override esp_log_format() to skip ESP-IDF's own formatting after the ESPHome logger hook is installed, since ESPHome does its own formatting. For early boot and constrained environments (ISR, cache disabled), format messages in ESPHome style with colors using a stack buffer.
