fix: skip NTP sync and mDNS in deep sleep wake path to reduce battery drain

The syncNTP() call blocks up to 5 seconds waiting for NTP response on
every deep sleep wake cycle (every 10 minutes). Combined with mDNS
startup, this added significant active WiFi time per cycle.

Fix: Add 'minimal' flag to WiFiManager::begin()/startStation(). In
the deep sleep wake path, skip NTP sync and mDNS entirely. The system
clock is already seeded from the hardware RTC at boot, which is
accurate enough for 30-day date window calculations.

Normal interactive boot still does full NTP sync + mDNS as before.
