Subject: [PATCH] refactor(pdf): replace ts-pattern match chains with satisfies
 Record maps

Two match chains in sections.tsx are replaced with plain lookup maps typed
via `satisfies Record<CustomSectionType, ...>` which preserves compile-time
exhaustiveness without the ts-pattern dependency. Remove ts-pattern from
packages/pdf/package.json.
