Subject: [PATCH 1/2] Add *.parquet to .gitignore
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Prevent accidental commit of large parquet data files (e.g., 691MB oc_isamples_pqg.parquet).

These files are too large for git and should be accessed via:
- Remote URLs (HTTP range requests)
- Local caching during development
- External data storage (Zenodo, Google Storage, etc.)

Subject: [PATCH 2/2] Add geocode search box to Cesium map
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Users can now paste a geocode PID (e.g., geoloc_04d6e816218b1a8798fa90b3d1d43bf4c043a57f) into a search box and the map will:
- Query the database for that geocode's coordinates
- Fly the camera to that location (2-second animation)
- Automatically trigger all data queries for that location

Implementation:
- Added Inputs.text search box with submit functionality
- Reactive cell watches searchGeoPid changes
- Uses Cesium camera.flyTo() for smooth navigation
- Sets clickedPointId after camera arrives to load data

This enables direct navigation to known geocodes without manual map clicking.

Test example PIDs:
- geoloc_04d6e816218b1a8798fa90b3d1d43bf4c043a57f (PKAP, 5 samples)
- geoloc_7a05216d388682536f3e2abd8bd2ee3fb286e461 (Larnaka, 0 samples)
