Consolidate fnconfig.ini across platforms

The default fnconfig.ini file is currently maintained separately for multiple FujiNet platforms. While platform-specific differences are minimal, each platform contains its own copy of the configuration file.

As a result:

• Common configuration changes must be applied to multiple files.
• Configuration files can drift out of sync over time.
• Some platforms may be missing updates present on others.
• Users may see inconsistent default settings, host lists, or behavior depending on platform.

A recent example is that some platforms ship with a shorter default Hosts list than others because their copies of fnconfig.ini have not received the same updates.

Solution

Create a single shared source for the common fnconfig.ini content.

Possible approaches include:

1. Maintain a single fnconfig.ini used by all platforms.
2. Create a shared/common fnconfig.ini and allow platform-specific files to extend or include it when platform-specific settings are required.

Benefits

• Ensures all platforms receive the same default configuration.
• Reduces maintenance effort by eliminating duplicate files.
• Prevents configuration drift between platforms.
• Makes it easier to add or modify default hosts and settings in the future.
