docs: add full wiki with 74 pages, assets, and CI workflow

Adds the complete TREK documentation wiki covering installation,
trip planning, admin panel, MCP/AI integration, addons, and operations.

Also fixes encrypt-at-rest gaps: mapbox_access_token, Synology
credentials, per-user webhook/ntfy tokens, and photo passphrases
are now rotated by migrate-encryption.ts and stored encrypted via
settingsService.

+# Places and Search
+
+Places are the building blocks of your trip. You can add them by searching, pasting a URL, entering coordinates, or importing a file.
+
+![Places sidebar](assets/PlaceAutocomplete.png)
+
+## Adding a place
+
+Click **+ Add Place** at the top of the Places sidebar to open the Place form. You can also **right-click anywhere on the map** to create a place at that exact location — the address is reverse-geocoded and pre-filled automatically.
+
+## Searching for a place
+
+Type in the search box at the top of the form. After 2 or more characters, with a 300 ms debounce, suggestions appear in a dropdown.
+
+- Use **↑ / ↓** to navigate results, **Enter** to select, **Esc** to dismiss.
+- Search results are biased toward the geographic center of your existing trip places. When those places span more than ~500 km, the bias is skipped.
+
+### With a Google Maps API key
+
+> **Admin:** A Google Maps API key is configured in [User-Settings](User-Settings).
+
+When a key is present, the autocomplete uses the Google Places API, which can return ratings, opening hours, photos, and phone numbers from Google's database.
+
+### Without a Google Maps API key
+
+TREK falls back to OpenStreetMap (Nominatim) automatically — no API key needed. A notice appears above the search box explaining that OpenStreetMap is in use and that photos, ratings, and opening hours are unavailable. Results include name, address, and coordinates.
+
+## Pasting a Google Maps URL
+
+Paste a `maps.app.goo.gl/…`, `goo.gl/maps/…`, or `maps.google.*/…` URL directly into the search box and press the search button. TREK resolves it server-side and populates the name, address, and coordinates.
+
+## Entering coordinates manually
+
+Type or paste a `lat, lng` pair (e.g. `48.8566, 2.3522`) into the **Latitude** field. TREK detects the comma-separated pair and fills both coordinate fields at once.
+
+## Place fields
+
+<!-- TODO: screenshot: Place form with all fields visible -->
+
+| Field | Notes |
+|---|---|
+| Name | Required |
+| Description | Free text |
+| Notes | Free text, max 2 000 characters |
+| Address | Free text |
+| Latitude / Longitude | Decimal degrees |
+| Category | Pick an existing category or type a new name to create one inline (default color `#6366f1`, icon `MapPin`) |
+| Start time / End time | Shown only when editing an existing place |
+| Website | URL |
+| File attachments | Images or PDFs — click the Paperclip icon or paste from the clipboard |
+
+Two inline warnings are shown when editing times: one if the end time is set to a value before or equal to the start time, and one if the times overlap with another place already assigned to the same day.
+
+## Importing multiple places
+
+Drag a `.gpx`, `.kml`, or `.kmz` file onto the Places sidebar to import all waypoints or features at once. You can also import a saved-list share URL using the **Import list** button in the sidebar header — both Google Maps and Naver Maps list URLs are supported.
+
+> **Admin:** Google Maps API key is set in [User-Settings](User-Settings). Without it, OSM search is used automatically.
