Enhance PocketBase workflow; fix installer scripts

Workflow: add push trigger for main branch on json/*.json and update the "Get JSON file for script" step to handle both workflow_dispatch and push events. The step now collects changed json/*.json files, validates each has a .slug with jq, ignores metadata/update-apps.json/versions.json, writes changed_app_jsons.txt, and sets a count output for downstream steps.

Installer & ct scripts: normalize indentation/formatting, ensure aliases.json and plugin-settings.json are initialized as {} and repos.json as [] when missing, and add missing trailing newlines. These changes improve robustness and shellcheck friendliness and make the workflow respond to direct pushes of app JSON files.
