Stage 1/3: add date+upload field groups; drop Stage 2 group labels

More pair-clustering across stages: Stage 1 gets four (Preliminary
Market Assessment, Preliminary Sources & Uses, Vision, Business
Concept), Stage 3 gets one (Site Letter of Intent). Stage 2 groups
drop their labels — the pair structure reads on its own and the
extra heading was visual noise.
