Separate S3 buckets for raw data and HTML exports (#41)

## Summary
Splits Cloudflare R2 bucket configuration into two distinct buckets for
better organization and access control:

- **CLOUDFLARE_R2_RAWDATA_BUCKET_NAME** (`sfs-json`): Stores source JSON
files from the API
- **CLOUDFLARE_R2_HTMLEXPORT_BUCKET_NAME** (`web`): Stores generated
HTML exports for public access

## Changes
- ✅ Updated `fetch-sfs-workflow.yml` to upload JSON to rawdata bucket
- ✅ Updated `html-export-workflow.yml` to download from rawdata and
upload HTML to export bucket
- ✅ Updated `github-pages-workflow.yml` to download JSON from rawdata
bucket
- ✅ Changed bucket names from secrets to repository variables for better
transparency

## Benefits
- Better organization with separate buckets for different data types
- Allows different retention policies and access controls per bucket
- More transparent configuration using variables instead of secrets for
non-sensitive data

## Required Setup
Before merging, add these two repository variables:
```bash
gh variable set CLOUDFLARE_R2_RAWDATA_BUCKET_NAME --body "sfs-json"
gh variable set CLOUDFLARE_R2_HTMLEXPORT_BUCKET_NAME --body "web"
```

Or via GitHub UI: Settings → Secrets and variables → Actions → Variables
tab
