feat(db): phase 4 group 6 — server component pages to Drizzle

Converts all 18 server component page files from Supabase client queries
to Drizzle ORM using asAdmin. Adds getSession() + redirect to the three
pages (hse/incidents, hse/incidents/[id], hse/dashboard) that lacked it.
Maps snake_case component prop shapes explicitly where required.
