* fix: ensure each file of the extension package satisfies linting rules and disable some rules where necessary
* fix: update relative imports to absolute imports throughout extension code with the defined tilde and at symbols
* fix: import the updated ui module from the front package to the chrome extension package to prevent eslint rules from breaking subject to the recent merged changes into main
