Chuck b0d65581df Fix/config save error handling (#150 )

* fix(docs): Add trailing newlines to documentation files

* fix(web): Resolve font configuration loading error on first page load

- Remove ineffective DOMContentLoaded listener from fonts partial (loads via HTMX after main page DOMContentLoaded)
- Add proper HTMX event handling with htmx:afterSettle for reliable initialization
- Add duplicate initialization protection flag
- Improve error handling with response validation and clearer error messages
- Add fallback initialization check for edge cases
- Ensure DOM elements exist before attempting initialization

Fixes issue where 'Error loading font configuration' appeared on first web UI load when opening fonts tab.

* fix(config): Update plugins_directory to plugin-repos in config template

The web-ui-info plugin is located in plugin-repos/ directory, but the
config template was pointing to plugins/ directory. This caused the
plugin to not be discovered on fresh installations.

- Changed plugins_directory from 'plugins' to 'plugin-repos' in config.template.json
- Matches actual plugin location and code default behavior
- Ensures web-ui-info plugin is available by default on fresh installs

* fix(config): Improve config save error handling

- Make load_config() failure non-fatal in save_raw_file_content
  - Wrapped reload in try-except to prevent save failures when reload fails
  - File save is atomic and successful even if reload fails
  - Logs warning when reload fails but doesn't fail the operation

- Improve error messages in API endpoints
  - Added detailed error logging with full traceback for debugging
  - Extract specific error messages from ConfigError exceptions
  - Include config_path in error messages when available
  - Provide fallback messages for empty error strings

- Enhance frontend error handling
  - Check response status before parsing JSON
  - Better handling of non-JSON error responses
  - Fallback error messages if error details are missing

Fixes issue where 'Error saving config.json: an error occured' was
shown even when the file was saved successfully but reload failed.

LED Matrix Web Interface V3

Modern, production web interface for controlling the LED Matrix display.

Overview

This directory contains the active V3 web interface with the following features:

Real-time display preview via Server-Sent Events (SSE)
Plugin management and configuration
System monitoring and logs
Modern, responsive UI
RESTful API

Running the Web Interface

Standalone (Development)

From the project root:

python3 web_interface/start.py

Or using the shell script:

./web_interface/run.sh

As a Service (Production)

The web interface can run as a systemd service that starts automatically based on the web_display_autostart configuration setting:

sudo systemctl start ledmatrix-web
sudo systemctl enable ledmatrix-web  # Start on boot

Accessing the Interface

Once running, access the web interface at:

Local: http://localhost:5000
Network: http://:5000

Configuration

The web interface reads configuration from:

config/config.json - Main configuration
config/secrets.json - API keys and secrets

API Documentation

The V3 API is available at /api/v3/ with the following endpoints:

Configuration

GET /api/v3/config/main - Get main configuration
POST /api/v3/config/main - Save main configuration
GET /api/v3/config/secrets - Get secrets configuration
POST /api/v3/config/secrets - Save secrets configuration

Display Control

POST /api/v3/display/start - Start display service
POST /api/v3/display/stop - Stop display service
POST /api/v3/display/restart - Restart display service
GET /api/v3/display/status - Get display service status

Plugins

GET /api/v3/plugins - List installed plugins
GET /api/v3/plugins/<id> - Get plugin details

Real-time Streams (SSE)

GET /api/v3/stream/stats - System statistics stream
GET /api/v3/stream/display - Display preview stream
GET /api/v3/stream/logs - Service logs stream

Development

When making changes to the web interface:

Edit files in this directory
Test changes by running python3 web_interface/start.py
Restart the service if running: sudo systemctl restart ledmatrix-web

Notes

Templates and static files use the v3/ prefix to allow for future versions
The interface uses Flask blueprints for modular organization
SSE streams provide real-time updates without polling
