refactor lora payload timing
...
Bump the batch payload codec to schema v4 with separate meter-time and UTC anchors, then use meter seconds for sparse batch slotting and receiver reconstruction.
Update the current 868 MHz bench configuration, allow ACKs from configured receiver short IDs, improve AP-to-STA recovery, quiet the test build, and document the changed protocol in the README.

sec(sender): ACK rate-limiting, unknown device-ID rejection, fuzz tests
...
- Add 500 ms minimum interval between accepted ACKs to mitigate replay floods
- Reject ACK packets from unrecognised device IDs (DeviceIdMismatch)
- Add test/test_security_fuzz: negative/boundary tests for decode_batch,
uleb128_decode, svarint_decode, lora_parse_frame entry points

feat(power): 1Hz chunked light-sleep; meter backoff; log throttling
...
- Replace delay() with light_sleep_chunked_ms() in sender idle path
(100ms chunks preserve UART FIFO safety at 9600 baud)
- Add ENABLE_LIGHT_SLEEP_IDLE build flag (default: on, fallback: =0)
- Meter reader task: exponential backoff on consecutive poll failures
(METER_FAIL_BACKOFF_BASE_MS..MAX_MS) to reduce idle Core-0 wakeups
- Configurable SENDER_DIAG_LOG_INTERVAL_MS (5s debug / 30s prod)
- Configurable METER_FRAME_TIMEOUT_CFG_MS, SENDER_CPU_MHZ
- New PlatformIO envs: lowpower, 868-lowpower, lowpower-debug
- Add docs/POWER_OPTIMIZATION.md with measurement plan and Go/No-Go
