Two-layer fix:
- NMEAParser: parse time fields from RMC sentences even when status
is void ('V'). The MIA-M10Q's battery-backed RTC provides time in
every sentence — we were discarding it along with the void location.
- GPSManager: allow first time sync without satellite lock. Subsequent
syncs still require sats>0 for accuracy. Year/epoch validation still
guards against garbage data from uninitialized modules.
Previously, time only appeared after WiFi connection (NTP via
configTzTime). Now the clock shows within seconds of boot using the
GPS module's RTC, then corrects when satellites lock.
- GPS time sync via UBlox MIA-M10Q (38400 baud auto-detect)
- Custom zero-dependency NMEA parser with XOR checksum validation
- Only trust GPS time when satellites > 0 (no stale RTC cache)
- DST-aware timezone picker at first boot (21 cities, POSIX TZ strings)
- Timezone also configurable in Settings > GPS/Time
- GPS Time on by default, GPS Location off by default (opt-in)
- Status bar: clock (top-left), Ratspeak.org (center), battery (right)
- 12h time default (no AM/PM), configurable 24h in settings
- NVS persistence of GPS time for approximate timestamps across reboots
- Fix factory reset Enter key bleed-through (600ms input guard)
- Fix hardcoded UTC-5 NTP timezone (now uses DST-aware POSIX TZ)
- Enable UBlox MIA-M10Q GPS on T-Deck Plus (HAS_GPS true)
- Custom zero-dependency NMEA parser (NMEAParser.h) with XOR checksum
- GPSManager: baud auto-detect (115200/38400/9600, 10s timeout),
settimeofday() sync every 60s, NVS time/position persistence
- GPS Time enabled by default, GPS Location disabled by default
(user must explicitly opt in via Settings)
- Replace status bar connectivity bars with clock display (top-left)
- Default 12h format without AM/PM, configurable 24h in Settings
- Add GPS/Time settings category: GPS Time, GPS Location,
UTC Offset (-12 to +14), 24h Time toggle
- Fix hardcoded UTC-5 NTP timezone to use configurable utcOffset
- Change status bar brand text to "Ratspeak.org"
