Fix Issue #18: Community settings now match admin panel configuration

## Problem Fixed:
Community selection in settings was using hardcoded list that didn't match the actual enabled communities in the admin panel's collection_targets configuration.

## Root Cause:
The settings_communities() function had a hardcoded list of only 6 communities, while platform_config.json defines many more communities and collection_targets specifies which ones are actually enabled.

## Solution:
- **Dynamic community loading** - Reads from platform_config.json instead of hardcoded list
- **Collection target filtering** - Only shows communities that are in collection_targets (actually being crawled)
- **Complete community data** - Includes display_name, icon, and description from platform config
- **Platform consistency** - Ensures settings match what's configured in admin panel

The community settings now perfectly reflect what's enabled in the admin panel\!
