feat(store&bottom-nav): add package entry tab tracking logic

1. add packageEntryTab state and mutation in vuex store
2. extract and track current/previous page's matching tab entry
3. update package entry tab state via store commit instead of local variable
4. optimize tab url parsing by stripping query parameters
