Blafrende Flag U1.0 - Project UNION

Based on:
- NodeMCU Blafrende Flag FasterServo v1.1
- UNION Consolidation v0.1
- Same ESP8266/NodeMCU migration model as TempMQTT U1.0

Architecture:
- UNION: language, shared web layout, WiFi, MQTT connection, System, Firmware and Info framework
- Project: servo motion, local test button, wind/speed configuration and project-specific MQTT topics

Board:
NodeMCU 1.0 (ESP-12E Module)

Libraries:
ESP8266 core, Servo, PubSubClient

Default hostname:
blafrende-flag.local

Setup network:
BlafrendeFlag-Setup

Default pins:
Servo D5 / GPIO14
Test button D2 / GPIO4
LED D1 / GPIO5

Important:
The original flag movement from v1.1 is retained, including the faster servo behavior.
