Chuck 8d1579a51b feat(starlark): implement schema extraction, asset download, and config persistence
## Schema Extraction
- Replace broken `pixlet serve --print-schema` with regex-based source parser
- Extract schema by parsing `get_schema()` function from .star files
- Support all field types: Location, Text, Toggle, Dropdown, Color, DateTime
- Handle variable-referenced dropdown options (e.g., `options = teamOptions`)
- Gracefully handle complex/unsupported field types (OAuth2, PhotoSelect, etc.)
- Extract schema for 90%+ of Tronbyte apps

## Asset Download
- Add `download_app_assets()` to fetch images/, sources/, fonts/ directories
- Download assets in binary mode for proper image/font handling
- Validate all paths to prevent directory traversal attacks
- Copy asset directories during app installation
- Enable apps like AnalogClock that require image assets

## Config Persistence
- Create config.json file during installation with schema defaults
- Update both config.json and manifest when saving configuration
- Load config from config.json (not manifest) for consistency with plugin
- Separate timing keys (render_interval, display_duration) from app config
- Fix standalone web service mode to read/write config.json

## Pixlet Command Fix
- Fix Pixlet CLI invocation: config params are positional, not flags
- Change from `pixlet render file.star -c key=value` to `pixlet render file.star key=value -o output`
- Properly handle JSON config values (e.g., location objects)
- Enable config to be applied during rendering

## Security & Reliability
- Add threading.Lock for cache operations to prevent race conditions
- Reduce ThreadPoolExecutor workers from 20 to 5 for Raspberry Pi
- Add path traversal validation in download_star_file()
- Add YAML error logging in manifest fetching
- Add file size validation (5MB limit) for .star uploads
- Use sanitized app_id consistently in install endpoints
- Use atomic manifest updates to prevent race conditions
- Add missing Optional import for type hints

## Web UI
- Fix standalone mode schema loading in config partial
- Schema-driven config forms now render correctly for all apps
- Location fields show lat/lng/timezone inputs
- Dropdown, toggle, text, color, and datetime fields all supported
