Add Smart Label port 10 active GNSS uplink decoder.

[StefanSmile]

Decode lorawan_gps_ul_ts_t (20-byte fix with status, lat/lon, altitude, timestamp, battery, TTF, PDOP, and satellites) and register GNSS/timestamp/battery features. Includes Zurich sample regression test.

Summary by CodeRabbit

• New Features

  • Added GNSS uplink decoding: extracts location (lat/lon), altitude, timestamp, battery voltage, and optional metrics (time-to-fix, PDOP, satellites) with validation and formatted JSON output.

• Tests

  • Added and extended tests covering Port 10 GNSS scenarios, feature flags, error cases, and JSON marshaling.

• Chores

  • Updated secrets baseline generated timestamp.

📝 Walkthrough

Walkthrough

Adds SmartLabel v1 port 10 GNSS uplink support: new Port10Payload type and JSON marshaling, decoder config with byte-to-value transforms (latitude/longitude/altitude/timestamp/TTF/PDOP/battery), extended tests for port 10, and updated .secrets.baseline entries and timestamp.

Changes

Port 10 GNSS Decoder Implementation

Layer / File(s)	Summary
Port10Payload type and marshaling pkg/decoder/smartlabel/v1/port10.go	Defines Port10Payload struct with GNSS/telemetry fields (status, latitude, longitude, altitude, timestamp, battery, optional TTF, PDOP, satellites), adds custom MarshalJSON, compile-time feature interface assertions, and getter methods.
Decoder port 10 configuration and transforms pkg/decoder/smartlabel/v1/decoder.go	Adds time import; registers case 10 in getConfig with field offsets/lengths and per-field transforms; replaces prior humidity transform with latitude, longitude, altitude, timestamp (Unix→UTC), gnssBattery, ttf (seconds→time.Duration), and pdop; sets GNSS/timestamp/battery feature flags.
Decoder test coverage for port 10 pkg/decoder/smartlabel/v1/decoder_test.go	Imports time; extends TestDecode, TestFeatures, and TestMarshal with port 10 cases (valid GNSS payloads, invalid-length error), and adds TestPort10Features to assert feature advertising and payload status.

Secrets Detection Baseline Update

Layer / File(s)	Summary
Secrets baseline refresh .secrets.baseline	Updates results["pkg/decoder/smartlabel/v1/decoder_test.go"] Hex High Entropy String hashed_secret/line_number entries and refreshes top-level generated_at timestamp.

In `@pkg/decoder/smartlabel/v1/port10.go`:
- Line 37: The Satellites field's validation is too strict and rejects valid
GNSS packets reporting 0–2 satellites; update the struct tag on Satellites (the
Satellites *uint8 field in port10.go) to either remove the validate tag entirely
or change it to allow 0 (e.g., validate:"gte=0,lte=27") so packets with 0–2
satellites are accepted while still capping at 27.
