Fix/remove compatible versions requirement (#171)

* fix(plugins): Remove compatible_versions requirement from single plugin install

Remove compatible_versions from required fields in install_from_url method
to match install_plugin behavior. This allows installing plugins from URLs
without manifest version requirements, consistent with store plugin installation.

* fix(7-segment-clock): Update submodule with separator and spacing fixes

* fix(plugins): Add onchange handlers to existing custom feed inputs

- Add onchange handlers to key and value inputs for existing patternProperties fields
- Fixes bug where editing existing custom RSS feeds didn't save changes
- Ensures hidden JSON input field is updated when users edit feed entries
- Affects all plugins using patternProperties (custom_feeds, feed_logo_map, etc.)
