feat(places): add self-hosted geocoding with Pelias (DACH)

New mana-geocoding service (port 3018) wraps a self-hosted Pelias
instance with LRU caching and OSM→PlaceCategory auto-mapping.
All geocoding queries stay within our infrastructure — no user
location data leaves the network.

Places module integration:
- Address autocomplete search in ListView (creates place with
  name, coords, address, category in one step)
- Address search + reverse geocoding button in DetailView
- Auto-fill address via reverse geocoding during tracking
- OSM category mapping (amenity:restaurant→food, shop:*→shopping, etc.)

# mana-geocoding
Self-hosted geocoding service. Wraps a local Pelias instance (DACH region) with caching and automatic OSM → PlaceCategory mapping. All geocoding queries stay within our infrastructure — no user location data leaves the network.
## Tech Stack
| Layer | Technology |
|-------|------------|
| **Runtime** | Bun |
| **Framework** | Hono |
| **Geocoding** | Pelias (self-hosted, Elasticsearch-backed) |
| **Data** | OpenStreetMap DACH extract (DE/AT/CH) |
| **Caching** | In-memory LRU (5000 entries, 24h TTL) |
## Port: 3018
## Quick Start
```bash
# 1. Start Pelias stack (first time: run setup.sh for data import)
cd services/mana-geocoding/pelias
docker compose up -d
# First time only:
chmod +x setup.sh && ./setup.sh
# 2. Start the Hono wrapper
cd services/mana-geocoding
bun run dev
```
## API Endpoints
All endpoints are public (no auth required) — the service is internal-only, not exposed to the internet.
| Method | Path | Description |
|--------|------|-------------|
| GET | `/api/v1/geocode/search?q=...` | Forward geocoding / autocomplete |
| GET | `/api/v1/geocode/reverse?lat=...&lon=...` | Reverse geocoding |
| GET | `/api/v1/geocode/stats` | Cache statistics |
| GET | `/health` | Health check |
### Search params
| Param | Required | Description |
|-------|----------|-------------|
| `q` | yes | Search query (min 2 chars) |
| `limit` | no | Max results (default 5, max 20) |
| `lang` | no | Language (default `de`) |
| `focus.lat` | no | Bias results towards this latitude |
| `focus.lon` | no | Bias results towards this longitude |
### Reverse params
| Param | Required | Description |
|-------|----------|-------------|
| `lat` | yes | Latitude |
| `lon` | yes | Longitude |
| `lang` | no | Language (default `de`) |
### Response format

## Category Mapping
The service maps OSM tags to our 7 PlaceCategories:
| PlaceCategory | OSM examples |
|---------------|-------------|
| `home` | building:residential, building:house, building:apartments |
| `work` | amenity:school, amenity:university, office:*, building:commercial |
| `food` | amenity:restaurant, amenity:cafe, shop:bakery, shop:supermarket |
| `shopping` | shop:*, amenity:marketplace |
| `transit` | railway:station, highway:bus_stop, amenity:parking, aeroway:* |
| `leisure` | tourism:*, leisure:park, amenity:cinema, sport:* |
| `other` | Everything else |
## Architecture
```
Client (Places module)
→ mana-geocoding (Hono, port 3018)
→ LRU cache check
→ Pelias API (port 4000)
→ Elasticsearch (port 9200)
```
## Configuration
```env
PORT=3018
PELIAS_API_URL=http://localhost:4000/v1
CORS_ORIGINS=http://localhost:5173,https://mana.how
CACHE_MAX_ENTRIES=5000
CACHE_TTL_MS=86400000
```
## Pelias Infrastructure
The Pelias stack runs as a separate docker-compose in `pelias/`:
- **elasticsearch** — Index storage (~500MB for DACH)
- **api** — HTTP API (port 4000)
- **libpostal** — Address parsing (port 4400)
- **Import containers** — Run once for initial data load, then stop
RAM usage (running): ~1.5GB (elasticsearch 512MB + api + libpostal)
## Code Layout
