- HTML: Add Wi-Fi scan results container to network.html
- Rust: Implement `wifi_scan_details()` with RSSI, channel, auth method
- API & UI: Fetch and display scan results in table format
- MQTT: Publish top 10 networks sorted by RSSI to `/wifi_scan`
- fix: use tagged enum serialization for TankError
- fix: rename TankInfo fields for consistent naming (volume_ml, pct, water_temp_c)
- renamed some fields for better clarity on contained value
- fix: use tagged enum serialization for MoistureSensorError and PumpError
- fix: flatten PlantInfo sensors to SensorTelemetry with top-level moisture_pct
- use crate::util::mk_static in network module
- use crate::util::mk_static in mqtt module
- use crate::util::mk_static in hal module
- remove dead mk_static macro from esp module
- Added `flow_interrupt_handler` for efficient interrupt processing.
- Replaced per-instance `flow_counter` with global atomic and mutex-based state (`FLOW_OVERFLOW_COUNTER`, `FLOW_UNIT`).
- Updated flow meter functions to leverage the new architecture for better modularity and thread safety.
- Switched debugging output from `println!` to `log` for improved logging consistency.
- Increased CAN measurement timeout to 5000ms for reliability.
- Updated `SAVEGAME_SLOT_SIZE` usage in backup handling for consistency.
- Refined moisture sensor frequency thresholds for better sensor calibration (400Hz-70kHz).
- Added `overcurrent_ma` field to pump results for capturing overcurrent data.
- Enhanced pumping logic to record and propagate overcurrent issues per plant.
- Updated `PumpState` and `PlantState` to handle overcurrent errors.
- Renamed `extra1` method and related calls to `fertilizer_pump` for clarity and better domain alignment.
- Updated HAL implementation to control `extra2` GPIO for fertilizer pump operations.
- Added build script trigger to refresh `VERGEN_BUILD_TIMESTAMP` on each build.
- Enhanced error detection with detailed status logging for bus-off, error warning, and passive errors.
- Added line breaks to CAN and RX error logs for better readability.
- Refined CAN transmission logic and error feedback, including buffer overflow handling.
- Simplified firmware timestamp frame creation and ensured successful sending.
