[F5:EC1] Expense Category Tab Data

[timebox: , complexity: ]

As a developer, I want to store and read a list of tab labels from active memory (Redux State) including preset labels including “All”, “Fixed”, and “Variable” so that the category tab label data is available throughout the app.

Locate the Redux state and the expense-category entry points that should own the tab labels. Define the state shape and trace how it is read across the app; the work is done when the preset labels “All”, “Fixed”, and “Variable” can be stored and read throughout the app.
