feat: add dash-leaflet, search bar and Carto API key fix

[t-kramer]

@FedericoTartarini @stefanoschiavon @giobetti

As follow-up on my comments in #276:

I am re-deploying and adding the changes made to development we discussed earlier, not asking for review on this one.

This brings main up to date with development: the dash-leaflet map (PR #276) plus everything since, including the Carto API key fix. Also added a few small follow-ups after merging: a search box to jump to a city/weather station by name (top-right of the map), a slightly taller map container, and an updated hint text reflecting the new search option.

Will redeploy right after this merges to remove the Carto API watermark. Let me know if anything looks off once it's live.

📝 Walkthrough

Walkthrough

The change adds a script to build a location dataset and a route to serve it. The selection page replaces its Plotly map with a clustered Dash Leaflet map that supports location search and marker-based modal content.

Changes

Location map

Layer / File(s)	Summary
Build location dataset scripts/build_locations_geojson.py	The script processes EnergyPlus and OneBuilding data, creates a location-name index, and writes compressed GeoJSON.
Serve location GeoJSON app.py	The /geojson/locations route serves the compressed dataset with gzip encoding and immutable caching headers.
Render and search locations Pipfile, .gitignore, pages/lib/global_element_ids.py, pages/select.py, assets/cluster.css, assets/manifest.json, tests/test_select.py	The selection page uses clustered Leaflet markers and a location autocomplete. Marker properties supply the modal URL and title. Supporting changes add the Dash Leaflet dependency, cluster styling, a search element ID, and an updated map test selector.
