GUI for custom scripts

**Describe the enhancement or feature you'd like**
A GUI to enable/disable/configure custom script parameter would be nice as it lessens the complexity of adding custom scripts and allows us to create presets.

**Additional context**
Start with a very simple base GUI first that can enable/disable scripts, then extend with features such as add/remove/edit and presets

**Todo**
- [x] Ability to toggle scripts on and off
- [x] Button to open scripts file
- [x] Sync with config file on change
- [x] Add links to script resources
- [ ] Abillity to add and remove new scripts
- [ ] Abillity to modify scripts
- [ ] Ability to manually run scripts right from the UI, for testing or other purposes
- [ ] Ability to turn specific scripts on/off (requires backend support)
- [ ] Script Presets

Start by reviewing the existing GUI, scripts file, and config file handling described in the issue. Compare the current interface with the remaining checklist items—adding, removing, modifying, and manually running scripts, per-script toggles, and presets—and clarify the required backend support before defining completion.
