fix(bulk-upload): form layout polish and drop zone sizing

- Drop zone box doubled: max-w-xl, larger icon (80px), bigger padding and text
- Title field wrapped in its own card (matches WhoWhenSection/DescriptionSection)
- Removed double-wrapping outer card around WhoWhenSection + DescriptionSection
- Added space-y-4 between form sections for consistent breathing room
- ScopeCard per-file label: text-accent → text-primary for legible contrast in light theme
