Enhance client reload process with new OpenAI compatibility support

- Added handling for OpenAI-compatible providers during client reload.
- Implemented client unregistration for old clients during reload.
- Improved logging for detailed client reload insights.

Expand `AuthDir` handling to support tilde (`~`) for home directory resolution

- Added logic to replace `~` with the user's home directory in `AuthDir`.
- Prevents errors when using `~` in configuration paths.
