feat: initial myprimal MQTT bridge service

Dynamic MySolem/MyIndygo IoT bridge with MQTT, Home Assistant
autodiscovery, and Homebridge EasyMQTT compatibility.

- Device discovery via MySolem API on startup (all modules/inputs/outputs)
- Configurable poll engine (fast/normal/slow buckets, per-input overrides)
- MQTT retained state publishing + HA autodiscovery payloads
- Unified manual command routing (linesControl vs sendManualModuleCommand)
- Runtime config via MQTT $config/set, persisted to config.json
- Expression override system (API-provided > hardcoded > passthrough)
- Minimal REST API: /health, /state, /control, /rediscover
- Docker deployment (Dockerfile + docker-compose.yml)
- 38 unit tests

+## Pool configuration
+
+| Field | Value |
+|---|---|
+| Pool ID | `5de53c1c7ed4c45c2cfe0688` |
+| Volume | 25 m³ |
+| Shape | rectangular 6 × 3 m, depth 1.4 m |
+| Filter | glass filter |
+| Treatment | stabilised chlorine tablets |
+| Chlorine regulation | manual |
+| pH regulation | automatic |
+| Installation | outdoor, no heating, no cover |
+
+Endpoint:
+```
+GET /maintenance-logs-data?moduleId=6481bcea8782b78554c02bed
+```
+Returns 25+ pool alerts, maintenance history, and `messages[0].pool` with full config.
+
+---
+
+## Sensors / Inputs
+
+| Input ID | Metric | Unit | Type code |
+|---|---|---|---|
+| `6481bcea8782b78554c02bef` | Water temperature | °C | 133 |
+
+> Sensor telemetry endpoint: `GET /remote/input/getComputedSensorData?inputId=...`  
+> Live readings (temp, pH, ORP, pressure) are in `maintenance-logs-data` under `pool.status`.
+

+
+## Outputs
+
+| Output ID | Name | Index |
+|---|---|---|
+| `6481bcea8782b78554c02bf1` | Station 1 (filtration pump) | 0 |
+| `6481bcea8782b78554c02bf2` | Station 2 | 1 |
+| `6481bcea8782b78554c02bf3` | Station 3 | 2 |

+
+## Filtration programs
+
+### Program 0 — Filtration (type 4, index 0)
+
+ID: `6481bcea8782b78554c02bf4`  
+Runs every day (weekDays: 127).
+
+| Window | Time range | Duration |
+|---|---|---|
+| Morning | 05:00–06:00 | 1h |
+| Midday | 12:00–14:00 | 2h |
+| Evening | 22:00–23:00 | 1h |
+| **Total/day** | | **4h** |
+
+Special features:
+- **Micro-filtration** (frost mode): triggers every 480 min for 10 min when temp < 5°C
+- **Temperature-adaptive schedules**: 2 schedules active (96 days + 31 days/year), each with 12 thresholds that adjust run windows based on pool temperature
+
+### Program 1 — Auxiliary/cyclic (type 2, index 1)
+
+ID: `6481bcea8782b78554c02bf5`  
+Active window: 21:30–22:30 (1h slot), cycle duration 5 min.  
+Likely electrolyser or secondary pump.
+
+### Program 2 — Unused (index 2)
+
+ID: `6481bcea8782b78554c02bf6`  
+No active windows configured.

+
+## Reading filtration schedule
+
+```
+GET /programs/modules?moduleIds=6481bcea8782b78554c02bed
+```
+
+Window times are in **minutes from midnight**. Duration (`on`) is in **seconds**.
+
+```python
+def mins_to_time(m): return f"{m//60:02d}:{m%60:02d}"
+def secs_to_human(s): h,m = divmod(s,3600); return f"{h}h{m//60:02d}m"
+
+for prog in data['programs']:
+    for w in prog['windows']:
+        if w['runningDays'] > 0:
+            print(f"{mins_to_time(w['start'])}–{mins_to_time(w['end'])}  {secs_to_human(w['on'])}")
+```
+
+---
+
+## Alerts & maintenance history
+
+```
+GET /maintenance-logs-data?moduleId=6481bcea8782b78554c02bed
+```
+
+Returns `{ code, messages: [...] }`. Each message has:
+- `poolAlertType`: `backwashReminder`, `backwashDone`, `poolLevelSensorCleaningReminder`, …
+- `priority`: `low` / `medium` / `high`
+- `state`: `read` / `unread`
+- `timestamp`: ISO 8601
+- `pool`: full pool config object (only on messages that have pool context)
+
+---
+
+## Notes
+
+- `remote/module/configuration` and `remote/module/informations` return `module_not_reachable` — the LRPC communicates via LoRa relay, not direct HTTP
+- `output/events` returns empty — past filtration run history is not stored server-side per event; the program schedule is the source of truth
+- The LRPC temperature input (type 133, unit 2) is distinct from the LRPS pool sensor temperature; both track pool water temp but from different probes
