chore: update capacitor config and script paths

- Update capacitor.config.json:
  - Change appId from com.brownspank.timesafari to app.timesafari
  - Add server configuration with cleartext enabled
  - Add plugins configuration for App URL handling
- Update script documentation paths:
  - Change ./openssl_signing_console.sh to /scripts/openssl_signing_console.sh
  - Change ./openssl_signing_console.rst to /doc/openssl_signing_console.rst

This change standardizes the app identifier and adds necessary
capacitor configurations for development, while also fixing script
documentation paths to use absolute references.
