Summary:
Depends on D20629. Ref T4900. Currently, the "Advanced Filter..." workflow on workboards (where you build a custom query) is inline in the main board controller.
This is because the filter flow depends on some of the board view state: we want to start with the current filter applied to the board, and preserve other state after you change the filter.
Now that `ViewState` can handle state management, we can separate this stuff out pretty easily.
Test Plan:
- Changed filters on a board.
- Applied a custom filter to a board.
- Changed the ordering of a board, then applied a custom filter. Verified "Cancel" and "Apply Filter" both preserve the order state.
- Changed the ordering of a board, then applied a custom filter, intentionally making a mistake in configuring the filter by entering an invalid date. Saw a dialog with an error. After correcting the error, saw state preserved properly.
