Batch 1: ToggleButtonGroup fixes, heading standardisation, spacing normalisation
- ToggleButtonGroup: increase label-to-options spacing (mb 1→2),
top-align button content (flex-start), fix selected border
CSS specificity by adding .Mui-selected in grouped selector
- Standardise all split-layout step headings from h4 to display3
(ProvidersStep, PackagesStep, PreviewStep, VenueStep, CoffinsStep,
CoffinDetailsStep) — matches D-A decision for brand warmth
- DateTimeStep: normalise section gaps (scheduling fieldset mb 3→4)
- CrematoriumStep: add subheading for consistency, normalise
witness section spacing (mb 3→4)
- Fix input label clipping in PackagesStep and DateTimeStep
(add pt: 0.5 to TextField containers for float-label clearance)
