Enhance CLI options and idle-killer functionality

- Added a `--update` option to the `up` command in the CLI for forced updates during warm ACTIVE states.
- Improved the idle-killer logic with new functions to check for reusable credentials and refresh settings on existing remote credentials.
- Enhanced the `seed_civitai` function to implement caching for model jobs, optimizing the provisioning process.
- Updated the installation script for Ollama to prevent unnecessary restarts when the service configuration has not changed.
- Added diagnostics for model job caching and improved error handling in various functions.
