Add eight nullable text columns to the hubspot_deal_data table to hold
planning and address-profiling attributes synced from HubSpot:
design_constraints, planning_comments, planning_status,
planning_suggested_approach, planning_authority, designated_area,
article_4_pd_rights, listed_building
Typed as text to match how the table already stores HubSpot
dropdown/enum-style properties (e.g. dampmould_growth, domna_survey_type).
