UI: de-duplicate top-bar and panel paint scripts

- Fixes missing check for unified brush in sculpt mode.
- Re-orders material first in gpencil paint mode
  (matching color-first for other paint modes).
- Avoid minor differences (missing tablet pressure options from topbar).
- Don't repeat properties already displayed in the topbar
  when opening the brush popover.
