SFMS Insights: Fire Weather Raster Visualization

[conbrad]

Adds new SFMS Insights page with interactive map visualization of fire weather raster data (GeoTIFF) from BC government object store.

Features:

• 6 Fire Weather Indices: FWI, DMC, DC, FFMC, BUI, ISI with proper color ramps and class breaks
• Dynamic Visualization: Hover tooltips showing pixel values, auto-updating legend per raster type
• Date Picker: ASA-style date picker for historical and forecast data
• Snow Layer: PMTiles-based snow coverage overlay
• Loading/Error States: Visual feedback during raster tile loading
• wps_tools.generate_sfms_cog script and launch config to selectively generate COGs for the frontend (currently ran for June 27, 2025)

Technical Implementation:

• Backend: FastAPI proxy endpoint for streaming S3 GeoTIFF files (bypasses CORS, supports Range requests, requires auth)
• Frontend: WebGLTile layers with dynamic color expressions, requesting cogs from object store proxy
• NoData Handling: Dual approach (GeoTIFF source parameter + color expression thresholds)
• Config-Driven: Centralized RASTER_CONFIG for labels and color breaks across all raster types

EPSG:3857 seems to be hard coded in a couple/few places. What do you think about creating a constant for it in geospatial.py?
