Allow workboard sorting and filtering to be saved as defaults

Summary:
Fixes T6641. This allows users who have permission to edit a project to use "Save as Default" to save the current order and filter as defaults for the project.

These are per-board defaults, and apply to all users. The rationale is that I think the best default ordering/filtering depends mostly on the board, not the viewer.

This seems to align with most requests in the task, although rationale is a bit light. But, for example, it seems reasonable you might want to change the default filter to "All Tasks" on a sprint board, so you can see what's in the "Done" column.

This also fixes some minor issues I ran into:

  - Herald could hit an issue while checking permissions if the project was a subproject and a non-member had a triggering rule.
  - "Advanced filter..." did not prefill with the current filter.

Test Plan:
  - Set default order and filter on a workboard.
  - Reloaded board, saw settings stick.
  - Tried to edit a board as an unprivileged user (disabled menu items, error).
  - Reviewed transaction log.
