- display the count in the UI
- add types for clearIntermediates mutation
- minor styling and verbiage changes

* feat(ui): use solid badge variant

consistent with the rest of the usage of badges

* feat(ui): update board ctx menu, add board auto-add

- add context menu to system boards - only open is select board. did this so that you dont think its broken when you click it
- add auto-add board. you can right click a user board to enable it for auto-add, or use the gallery settings popover to select it. the invoke button has a tooltip on a short delay to remind you that you have auto-add enabled
- made useBoardName hook, provide it a board id and it gets your the board name
- removed `boardIdToAdTo` state & logic, updated workflows to auto-switch and auto-add on image generation

* feat(db, api): clear intermediates now clears all of them

* feat(ui): make reset webui text subtext style
